Microchip Tech Adds Flash Data Memory To Baseline PIC® Microcontroller Architecture
Microchip Technology Inc. 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 – the company claims that engineers now have a diverse feature set to select from when integrating digital intelligence in low-cost applications.
Through the integration of FDM and analog functionality onto its Baseline 8- and 14-pin microcontrollers, Microchip states that its 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; 25mA source/sink current IO; low power (100nA) sleep current; wide operating voltage range from 2 to 5.5V; one 8-bit timer, and one watchdog timer; In Circuit Serial Programming™ (ICSP™) technology for programming after placement on a board; and a package sizes as small as 2x3mm DFN.
The new Baseline PIC microcontrollers are said to 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).
Both devices are available for general sampling and volume production. In 10,000-unit quantities, the PIC12F519 is $0.56 each, and the PIC16F526 is $0.64 each.
