P80C32
Description
TEMIC’s 80C52 and 80C32 are high performance CMOS versions of the 8052/8032 NMOS single chip 8 bit µC.
Key Features
- Package sizes are not to scale
- Memory that use 16 bit addresses (MOVX @DPTR)
- In this application, it uses strong internal pullups when emitting 1’s
- During accesses to external Data Memory that use 8 bit addresses (MOVX @Ri), Port 2 emits the contents of the P2 Special Function Register
- It also receives the high-order address bits and control signals during program verification in the 80C52
- Port 2 can sink/source three LS TTL inputs
- It can drive CMOS inputs without external pullups
- VCC Supply voltage during normal, Idle, and Power Down operation
- Port 0 Port 0 is an 8 bit open drain bi-directional I/O port
- Port 0 pins that have 1’s written to them float, and in that state can be used as high-impedance inputs
