Description

The SPL61A, an 8-bit CMOS single chip microprocessor, contains RAM, ROM, I/Os, interrupt/wakeup controller, 8-bit PWM audio output, UART and automatic display controller/driver for LCD. With a dual channel PWM driver, attractive sound effects can be generated easily. A built-in UART speeds up data transmission between two chips. Furthermore, a software controllable standby switch is also built-in to save power consumption. The great amount of ROM can be used to store both program and audio data. (The speech duration is approximately 18 seconds at 7KHz sampling rate by using 4-bit ADPCM). The SPL61A is designed with state-of-the-art technology to fulfill the requirements of LCD applications especially hand-held products
