1. GENERAL DESCRIPTION
The W588Bxxx is a 8-bit microcontroller-based speech synthesizer with PWM mode output to drive speaker directly. It is suitable for multi-tasking toy application. The W588Bxxx family contains several items with different playback duration as shown below: Item *Duration Item Duration Item Duration
Note: *: The duration time is based on 5-bit MDPCM at 6KHz sampling rate. The firmware library and program code have been excluded from user's ROM space for the duration estimation.

3. PIN DESCRIPTION
NAME VSS1 PWM+/DAC PWMVDD1 VDD /RESET TEST *OP0[3:0] I/O O O I I O DESCRIPTION Negative power supply for PWM PWM driver positive output / DAC output. PWM driver negative output Positive power supply for PWM Positive power supply Active low reset pin, to reset whole device. Test pin, internally pulled low. Output port. The pins of OP0 are Inverter-type output. * * BP0[7:4] **BP0[0:3] I/O * I/O multiplexed port. As output port, the pins can be set as open-drain type or CMOS type. As input port, the pins can be set with pull-high resistor or not. Interrupt will be generated to release IC from STOP mode upon triggering. When BP0[7] is used as output pin, it can be the IR transmission carrier output for IR applications.
* VSS OSC I
Negative power supply Connect ROSC to Vss to generate the master clock
*: Only for W588B003~B015 **: Only for W588B020~B120

Notes: 1. 2. 3. 4. 5. 6. 7.
The typical value of Rosc is 160 K for 8MHz and 300 K for 4MHz and should be connected to GND (VSS). In PCB layout, VSS1 should be connected to VSS; VDD1 should be connected to VDD. The Rs value is suggested in 270 ~ 1K to limit too large SPK+ output current flowing into transistor. The capacitor, 0.1uF, shunted between VDD/VDD1 and GND (VSS/VSS1) is necessary. The 10 and 4.7uF between VDD, VDD1 and GND are optional to reduce probability of latch-up occurring. The I/O in W588B020~B120 is BP00~BP07. The above application circuits are for reference only. No warranty for mass production.
