TMP80C39P-6
Description
The TMP80C49P-6 is a single chip microputer fabricated in Silicon Gate CMOS technology which provides internal 8-bit parallel architecture.
Key Features
- VSS VCC(+SV) TI P27 P26 P25 P 24 PI?
- PIO-P17 (Input/Output) Port 1 8-bit quasi-bidirectional port (Internal Pullup _ SOK0 )
- P20-P27 (Input/Output) Port 2 8-bit quasi-bidirectional port (Internal Pullup ~ SOK0 )
- DBa-DB 7 (Input/Output, Tri-State) True bidrectional port which can be written or read synchronously using the RD, WR strobes
- The port can also be statically latched
- Also contains the address and data during an external RAM data store instruction, under control of ALE, RD, and WR
- TO (Input/Output) Input pin testable using the conditional transfer instructions JTO and JNTO
- TO can be designated as a clock output using ENTO CLK instruction
- TO is also used during programming
- Tl (Input) Input pin testable using the JTl and JNTl instruction
