TRSP(M)5080A General Descriptions:
TRSP(M)5080A 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 program ROM is 8K words and data ROM size is 240K byte. The maximum working SRAM is (128+2) nibbles. It is provided with total 12 software programmable I/O Ports.

Wakeup function for power-down mode:
-HALT mode wakeup source: Port A, Port B and Port E/CE can wake-up from HALT mode to NORMAL mode and executing wake-up sub-routine program.
8 input/output pins: Port A and Port B can be defined as input or output port bit by bit.
4 input/output ports or 4 input only ports or 4 output only ports “Port CE/E/C” defined by option:
-If input only ports are employed, Port E defined as input only ports.
-If output only ports are employed, Port C defined as output only ports.
-If input/output ports are selected, Port CE defined as input/output ports bit by bit.
