TRSP5006A General Descriptions：
TRSP5006A 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 includes a low cost, high performance CMOS micro-processor. The clock frequency of this up is typically 8.192 (±3%) MHz. This chip operates over a wide voltage range of 2.0V~5.5V. It contains program ROM (PROM) and data ROM (DROM) inside.
The maximum program ROM is 4K words and maximum data ROM size is 33K byte. The maximum working SRAM is (64+2) nibbles. It is provided with total 4 software programmable I/O Ports.
