introduction str73xf 4/40 high speed flash memory the flash program memory is organized in 32-bit wide memory cells which can be used for storing both code and data constants. it is accessed by cpu with zero wait states @ 36 mhz. the str7 embedded flash memory can be programmed using in-circuit programming or in-application programming. the flash memory endurance is 10k write/erase cycles and the data retention is 20 years at 55c. iap (in-application programming): the iap is the ability to re -program the flash memory of a microcontroller while the user program is running. icp (in-circuit programming): the icp is the ability to prog ram the flash memory of a microcontroller using jtag protocol while the device is mounted on the user application board. the flash memory can be protected against different types of unwanted access (read/write/erase). there are two types of protection: sector write protection flash debug protection (locks jtag access) flexible power management to minimize power consumption, you can program the str73xf to switch to slow, wfi lpwfi, stop or halt modes depending on the current system activity in the application. flexible clock control two clock sources are used to drive the microcontroller, a main clock driven by an external crystal or ceramic resonator and an internal ba ckup rc oscillator that operates at 2mhz or 32 khz. the embedded pll can be configured to generate an internal system clock of up to 36 mhz. the pll output frequency can be programmed using a wide selection of multipliers and dividers. voltag e regulators the str73xf requires an external 4.5 to 5.5v power supply. there are two internal voltage regulators for generating the 1.8v power supply needed by the core and peripherals. the main vr is switched off and the low power vr switched on when the application puts the str73xf in low power wait for interrupt (lpwfi) mode. low voltage detectors the voltage regulator and flash modules each have an embedded lvd that monitors the internal 1.8v supply. if the voltage drops be low a certain threshold, the lvd will reset the str73xf. note: an external power-on reset must be provided ensure the microcontroller starts-up correctly.
str73xf introduction 5/40 1.2 on-chip peripherals can interfaces the three can modules are compliant with the can specification v2.0 part b (active). the bit rate can be programmed up to 1 mbaud. these are not available in the str735 and str736. dma 4 dma controllers, each with 4 data streams manage memory to memory, peripheral to memory and memory to peripheral transfers. the dma requests are connected to tim timers, bspi0, bspi1, bspi2 a nd adc. one of the streams can be co nfigured to be triggered by a software request, independently from any peripheral activity. 16-bit timers (tim) each of the ten timers (six in 100-pin devices) have a 16-bit free-running counter with 7-bit prescaler, up to two input capture/output compare functions, a pulse counter function, and a pwm channel with selectable frequency. this provides a total of 16 independent pwms (12 in 100-pin devices) when added with the pwm modules (see next paragraph). pwm modules (pwm) the six 16-bit pwm modules ha ve independently programmab le periods and duty-cycles, with 5+3 bit prescaler factor. timebase timers (tb) the three 16-bit timebase timers with 8-bit prescaler for general purpose time triggering operations. realtime clock (rtc) the rtc provides a set of continuously running counters driven by separate clock signal derived from the main oscillator. the rtc can be used as a general timebase or clock/calendar/alarm function. when the str73xf is in lpwfi mode the rtc keeps running, powered by the low power voltage regulator. uarts the 4 uarts allow full duplex, asynchronous, communications with external devices with independently programmable tx and rx baud rates up to 625k baud. buffered serial perip heral interfaces (bspi) each of the three bspis allow full duplex, synchronous communica tions with external devices, master or slave communication at up 6 mb/s (@36 mhz system clock). i 2 c interfaces the two i 2 c interfaces provide multi-master and slave functions, support normal and fast i 2 c mode (400 khz) and 7 or 10-bit addressing modes. a/d converter the 10-bit analog to digital converter, converts up to 16 channels in single-shot or continuous conversion modes (12 channels in 100-pin devices). the minimum conversion time is 3us.
introduction str73xf 6/40 watchdog the 16-bit watchdog timer protects the application against hardware or software failures and ensures recovery by generating a reset. i/o ports up to 112 i/o ports (72 in 100-pin devices) are programmable as general purpose input/output or alternate function. external interrupts and wake-up lines 16 external interrupts lines are available for application use. in addition, up to 32 external wakeup lines (18 in 100-pin devices) can be used as general purpose interrupts or to wake- up the application from stop mode.

package characteristics str73xf 36/40 4.1.1 power considerations the average chip-junction temperature, t j , in degrees celsius, may be calculated using the following equation: t j = t a + (p d x ja )(1) where: ?t a is the ambient temperature in c, ? ja is the package junction-to-ambient thermal resistance, in c/w, ?p d is the sum of p int and p i/o (p d = p int + p i/o ), ?p int is the product of i dd and v dd , expressed in watt. this is the chip internal power, ?p i/o represents the power dissipation on input and output pins; user determined. most of the time for the applications p i/o < p int and may be neglected. on the other hand, p i/o may be significant if the device is config ured to drive continuously external modules and/or memories. an approximate relationship between p d and t j (if p i/o is neglected) is given by: p d = k / (t j + 273c) (2) therefore (solving equations 1 and 2): k = p d x (t a + 273c) + ja x p d 2 (3) where: ? k is a constant for the particular part, which may be determined from equation (3) by measuring p d (at equilibrium) for a known t a. using this value of k, the values of p d and t j may be obtained by solving equations (1) and (2) iteratively for any value of t a table 16. thermal characteristics symbol description package value (typical) unit ja thermal resistance junction-ambient lfbga144 tbd c/w tqfp144 40 tqfp100 55

known limitations str73xf 38/40 6 known limitations 6.1 low power wait for interrupt mode when the str73x device is put in low power wait for interrupt mode (lpwfi), the flash goes into low power mode or power down mode, depending on the setting of the pwd bit in the flash control register 0 (default is ?0?, low power mode). this default mode can create excessive voltage conditions on the transistor gates and may affect the long term behavior of the low power mode circuitry. workaround there is no workaround. if low power wait for interrupt mode is used, it is strongly suggested to configure the flash to enter power down mode (bit pwd = ?1?).
