TRSP(M)4080A General Descriptions:
TRSP(M)4080A series are 4-bits micro-controller which could play 2 channel melody or 2 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. These chips operate 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 248K/240K 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).
