Microchip Technology Adds Flash Data Memory To The Baseline PIC Microcontroller Architecture

Chandler, AZ - Microchip Technology Inc. recently announced the first two Baseline 8-bit Flash PIC microcontrollers with non-volatile Flash Data Memory (FDM) in 8- and 14-pin packages. These additions supplement the variety of integrated low pin count microcontrollers in the Baseline PIC microcontroller family. With the availability of 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—engineers now have a diverse feature set to select from when integrating digital intelligence in low-cost applications.

Design engineers are constantly looking for cost-effective ways to increase functionality, without having to add complexity to their designs. Through the integration of 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. Additionally, designers can replace discrete analog components with the digital intelligence and reprogrammability of a microcontroller.

"The Baseline Family of PIC microcontrollers remain the most cost-effective and easiest to use solution for embedded-control functions and systems," said Steve Drehobl, vice president of the Security, Microcontroller and Technology Development Division. "The addition of the industry's highest-endurance Flash Data Memory further reduces the total system cost for many entry-level applications."

Other significant features of the PIC12F519 and PIC16F526 include:

• 64 bytes of non-volatile Flash Data Memory
• 1K instructions (x12-bit program words) of Flash program 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
• In Circuit Serial Programming (ICSP) technology for programming after placement on a board
• Package sizes as small as 2x3 mm DFN

The new Baseline PIC microcontrollers form the basic building blocks for a wide variety of systems across a broad range of markets. Their integrated memory and analog functionality makes these microcontrollers well suited for applications such as battery-operated products, power supplies, and identification tags. Additional example applications for the Baseline PIC microcontroller family include: Consumer Electronics (standby power control, power-sequencing infrared receivers, handheld products, device authentication); Mechatronics (includes smart switches, mode selectors, remote I/Os, electric pumps, compressors); Home Automation (light switching and dimming, thermostats, security systems); and Small Home Appliances (blenders, toasters, coffee machines and electric toothbrushes).
