TRSP(M)4169A General Descriptions:
    TRSP(M)4169A series are 4-bits micro-controller which could play 4 channel melody or 4 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 4.096/8.192 (±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 8K/16K words and data ROM size is 496K/480K bytes. The maximum working SRAM is (128+2) nibbles. It is provided with total 16 software programmable I/O ports, 4 output only ports and a 13 levels low voltage detector (LVD).
