PIC12C671T-04I/SM

The PIC12C67X devices are low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers with integrated analog-to-digital (A/D) converter and EEPROM data memory.

All PICmicro microcontrollers employ an advanced RISC architecture. The PIC12C67X microcontrollers have enhanced core features, eight-level deep stack, and multiple internal and external interrupt sources. The separate instruction and data buses of the Harvard architecture allow a 14-bit wide instruction word with the separate 8-bit wide data. The two stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches, which require two cycles. A total of 35 instructions (reduced instruction set) are available. Additionally, a large register set gives some of the architectural innovations used to achieve a very high performance.

PIC12C67X microcontrollers typically achieve a 2:1 code compression and a 4:1 speed improvement over other 8-bit microcontrollers in their class.

The PIC12C67X devices have 128 bytes of RAM, 5 I/O pins and 1 input pin. In addition a timer/counter is available. Also a 4-channel, high-speed, 8-bit A/D is provided. The 8-bit resolution is ideally suited for applications requiring low-cost analog interface, (i.e., thermostat control, pressure sensing, etc.).

The PIC12C67X devices have special features to reduce external components, thus reducing cost, enhancing system reliability and reducing power consumption. The Power-On Reset (POR), Power-up Timer (PWRT), and Oscillator Start-up Timer (OST) eliminate the need for external reset circuitry. There are five oscillator configurations to choose from, including INTRC precision internal oscillator mode and the power-saving LP (Low Power) oscillator mode. Power saving SLEEP mode, Watchdog Timer and code protection features improve system cost, power and reliability. The SLEEP (power-down) feature provides a power-saving mode. The user can wake-up the chip from SLEEP
