TRSP&M5341A,TRSM5271A OTP-type Speech IC 1 . TRSP&M5341A,TRSM5271A G e n e r a l D e s c r i p t i o n s TRSP&M5341A,TRSM5271A 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 16K words and maximum data ROM size is 1024K byte. The maximum working SRAM is (256+2) nibbles. It is provided with total 16 software programmable I/O ports and 4 output only ports. 2 . TRSP&M5341A,TRSM5271A F e a t u r e s  Operating voltage: 2.
