TRSP30XXA series (TRSP3006A/TRSP3011A/TRSP3020A/TRSP3040A, TRSP3080A) General Descriptions:
TRSP30XXA series (TRSP3006A/TRSP3011A/TRSP3020A/TRSP3040A, TRSP3080A) 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 words and data ROM size is 248K bytes. The maximum working SRAM is (96+2) nibbles. It is provided with total 4 software programmable I/O Ports and a 13 levels low voltage detector (LVD).
