TRSP2020A Datasheet | ChipSourceTek

TRSP(M)2020A OTP-type Speech IC 1 . General Descriptions TRSP(M)2020A series are 4-bits micro-controller which could play 1 channel ADPCM with PWM direct drive circuit. PWM resolution is 8/10/12 bits. They include a low cost, high performance CMOS micro-processor. The clock frequency of this up is typically 4.096 (±3%)MHz. This chip operates over a wide voltage range of 1.5V~5.5V. It contains program ROM (PROM) and data ROM (DROM) inside. The program ROM is 4K/8K words and data ROM size is 56K/48K bytes. The maximum working SRAM is (64+2) nibbles. It is provided with total 4 software programmable I/O Ports. 2 .
