Microchip Microcontrollers Feature Non-Volatile Flash Data Memory

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.
