Easy interfacing to faster microcontrollers
Microchip has added two new devices to its PIC16C92X family of 8bit one-time-programmable microcontrollers with integrated liquid-crystal display controller.
Microchip's baseline PIC devices are extensively used in many cost-sensitive applications and Flash memory can increase development efficiencies and reduce total system costs.
The new PIC16F54, PIC16F57, PIC16F505, PIC12F508 and PIC12F509 offer customers the benefits of reprogrammable Flash memory via an easy migration path from Microchip's existing OTP devices, with equivalent price points and identical pin-counts in 8-, 14-, 18-, 20- and 28-pin packages.
Additional enhanced features on these new microcontrollers include an improved internal oscillator, wider operating voltage of 2-5.5V, improved reset functionality, and smaller (MSOP) packaging for the PIC12F508 and PIC12F509.
The main features of these PIC microcontrollers include: standard Flash program memory; a 4MHz internal oscillator; the baseline 12bit core with 33 instructions and two stack levels; 25mA source/sink current I/O; low power (100nA) sleep current; one 8bit timer (TMR0); watchdog timer (WDT); in-circuit serial programming (ICSP) capability; power on reset; and a power-saving sleep mode.
The new PIC devices form the basic building blocks for a wide variety applications including: logic control (any form of delay, smart gates, signal conditioning, simple state machines, encoders/decoders, I/O expanders and small peripheral logic functions on larger PC boards); mechatronics (smart switches, mode selectors, remote I/Os, timers, LED flashers and any other form of mechanical timer or switch); waveform generation (traditional 555 timer applications such as PWMs, remote control encoders, pulse generation, programmable frequency source and replacements for resistor-programmable oscillators); and small home appliances (blenders, toasters, coffee machines and electric toothbrushes).
All five devices are available for sampling and volume production is planned for August.
