|Microchip Technology Expands Small PIC® Microcontrollers With 20-Pin
Family and Additional Capabilities|
CHANDLER, Ariz., - Microchip Technology Inc.,
announced four new Flash 8-bit PIC® microcontrollers, which offer a cost-effective and code-compatible migration
path from existing 8- and 14-pin package options to 20-pin microcontrollers with a richer set of peripherals. These
new microcontrollers provide engineers with enhanced features such as steering-capable pulse-width modulation (PWM)
and a synchronous serial port with address-masking for I2C™, while offering additional program and data memory.
Engineers are faced with a continuous challenge of designing smaller products with more functionality in a
shorter time. Additionally, consumers expect higher quality levels, lower cost and longer battery life. Microchip’s
new PIC16F685/687/689/690 help solve these design challenges with smaller 4x4 QFN package options, easy migration
from other PIC microcontrollers to shorten the design time, and several new enhancements to increase functionality
while reducing total system cost. The four new microcontrollers also incorporate Microchip’s nanoWatt Technology
features for more control over the power consumption of the microcontroller.
four new PIC microcontrollers, Microchip is demonstrating its commitment to continuous improvement and innovation in
our low pin count 8-bit family,” said Steve Drehobl, vice president of Microchip’s Security, Microcontroller and
Technology Division. “By adding new microcontrollers with enhanced feature sets to our code-compatible portfolio, we
are making it easy for customers to start their next design with PIC microcontrollers.”
PIC16F685/687/689/690 microcontrollers serve a broad market, including the following example applications:
battery-powered devices (security systems, smoke and CO detectors, handheld devices); power conversion (power
supplies, DC/DC converters, battery chargers); and motor control (industrial, home appliances, power tools).
Several of the onboard peripherals were enhanced to provide greater flexibility and ease of
use for design engineers. These enhancements include a new comparator module with more internal and external
connections, and an analog-to-digital converter (ADC) with up to 12 channels. Additionally, the onboard I2C
synchronous serial port has address masking to support multiple addresses. The enhanced capture/compare/PWM module
incorporates PWM steering, allowing output to multiple pins under software control – a feature that provides greater
layout flexibility for motor control and power supply applications. Another significant feature is the
software-enabled Brownout Reset, which enables designers to significantly reduce standby current consumption in
sleep. Additional key features include:
• Capability of supporting the newly released
• 8 MHz, software-selectable internal oscillator
LIN-capable Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART)
channel, 10-bit ADC
• Two comparators with set-reset latch mode
0.6 volt internal bandgap reference
• Ultra Low Power Wake-up
Extended Watchdog Timer
• Enhanced low-power Timer 1 with Gate Control
Development Tool Support
The four new devices are supported by the full suite of
Microchip’s development tools, including the PICkit™ 2 Starter Kit, MPLAB® IDE (Integrated Development Environment),
and the low-cost MPLAB ICD 2 (In-Circuit Debugger).
