PIC12C67X
1.0 GENERAL DESCRIPTION
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 (EEPROM on PIC12CE67X versions only). 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, 16 bytes of EEPROM data memory (PIC12CE67X only), 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. Powersaving 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 through several external and internal interrupts and resets. A highly reliable Watchdog Timer with its own on-chip RC oscillator provides protection against software lock-up. A UV erasable windowed package version is ideal for code development, while the cost-effective One-TimeProgrammable (OTP) version is suitable for production in any volume. The customer can take full advantage of Microchip's price leadership in OTP microcontrollers, while benefiting from the OTP's flexibility.
1.1
Applications
The PIC12C67X series fits perfectly in applications ranging from personal care appliances and security systems to low-power remote transmitters/receivers. The EPROM technology makes customizing application programs (transmitter codes, appliance settings, receiver frequencies, etc.) extremely fast and convenient, while the EEPROM data memory (PIC12CE67X only) technology allows for the changing of calibration factors and security codes. The small footprint packages, for through hole or surface mounting, make this microcontroller series perfect for applications with space limitations. Low-cost, low-power, high performance, ease of use and I/O flexibility make the PIC12C67X series very versatile even in areas where no microcontroller use has been considered before (i.e., timer functions, replacement of "glue" logic and PLD's in larger systems, coprocessor applications).
1.2
Family and Upward Compatibility
The PIC12C67X products are compatible with other members of the 14-bit PIC16CXXX families.
1.3
Development Support
The PIC12C67X devices are supported by a fullfeatured macro assembler, a software simulator, an incircuit emulator, a low-cost development programmer and a full-featured programmer. A "C" compiler and fuzzy logic support tools are also available.
