www.DataSheet4U.com 80C32/80C52 CMOS 0 to 44 MHz Single Chip 8–bit Microntroller Description TEMIC’s 80C52 and 80C32 are high performance CMOS versions of the 8052/8032 NMOS single chip 8 bit µC. The fully static design of the TEMIC 80C52/80C32 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data. The 80C52 retains all the features of the 8052 : 8 K bytes of ROM ; 256 bytes of RAM ; 32 I/O lines ; three 16 bit timers ; a 6-so.

www.DataSheet4U.com 80C32/80C52 CMOS 0 to 44 MHz Single Chip 8–bit Microntroller Description TEMIC’s 80C52 and 80C32 are high performance CMOS versions of the 8052/8032 NMOS single chip 8 bit µC. The fully static design of the TEMIC 80C52/80C32 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data. The 80C52 retains all the features of the 8052 : 8 K bytes of ROM ; 256 bytes of RAM ; 32 I/O lines ; three 16 bit timers ; a 6-source, 2-level interrupt structure ; a full duplex serial port ; and on-chip oscillator and clock circuits. In addition, the 80C52 has 2 software-selectable modes of reduced activity for further reduction in power consumption. In the idle mode the CPU is frozen while the RAM, the timers, the serial port and the interrupt system continue to function. In the power down mode the RAM is saved and all other functions are inoperative. The 80C32 is identical to the 80C52 except that it has no on-chip ROM. TEMIC’s 80C52/80C32 are manufactured using SCMOS process which allows them to run from 0 up to 44 MHz with Vcc = 5 V. TEMIC’s 80C52 and 80C32 are also available at 16 MHz with 2.7 V < VCC < 5.5 V.

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. Port 0 is also the multiplexed low-order address and data bus during accesses to external Program and Data Memory. In this application it uses strong internal pullups when emitting 1’s. Port 0 also outputs the code bytes during program verification in the 80C52. External pullups are required during program verification. Port 0 can sink eight LS TTL inputs. Port 3 Port 3 is an 8 bit bi-directional I/O port with internal pullups. Port 3 pins that have 1’s written to them are pulled high by the internal pullups, and in that state can be used as inputs. As inputs, Port 3 pins that are externally being pulled low will source current (ILL, on the data sheet) because of the pullups. It also serves the functions of various special features of the TEMIC 51 Family, as listed below.
