Microchip Microcontrollers Feature Non-Volatile Flash Data Memory

Posted by Ken Cheung in Microcontrollers on Tuesday, January 8, 2008

By integrating non-volatile Flash Data Memory (FDM) and analog functionality onto its Baseline 8- and 14-pin microcontrollers, Microchip’s PIC12F519 (8-pin) and PIC16F526 (14-pin) provide a cost-effective option for many design engineers to store configuration and calibration data, counters or small look-up tables without external non-volatile memory. In addition, designers can replace discrete analog components with the digital intelligence and reprogrammability of a microcontroller. The microcontrollers features 64 bytes of data memory — combined with an 8 MHz internal oscillator, a Device Reset Timer (DRT), up to three channels of 8-bit Analog-to-Digital Conversion (ADC), and up to two comparators.

Microchip's PIC12F519 and PIC16F526 Baseline PIC MicrocontrollersAdditional features of the PIC12F519 and PIC16F526:

  • 1K instructions (x12-bit program words) of Flash program memory
  • 64 bytes of non-volatile Flash Data Memory
  • 41 bytes to 67 bytes of data RAM memory
  • Up to two comparators
  • Up to 3 channels of 8-bit ADC
  • 1.125 ms DRT
  • Precision internal oscillator, operating at up to 8 MHz
  • 25 mA source/sink current IO
  • Low power (100 nA) sleep current
  • Wide operating voltage range from 2 to 5.5 volts
  • One 8-bit timer, and one watchdog timer
  • Package sizes as small as 2×3 mm DFN
  • In Circuit Serial Programmingä (ICSPä) technology for programming after placement on a board

Both devices are available today in the package options listed below for general sampling and volume production. In 10,000-unit quantities, the PIC12F519 is $0.56 each, and the PIC16F526 is $0.64 each.

  • PIC12F519: 8-pin PDIP, MSOP, SOIC and 2×3 mm DFN package options
  • PIC16F526: 14-pin PDIP, SOIC and TSSOP package options
