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.

“With these 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.”

The new 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 PMBus™ protocol

• 8 MHz, software-selectable internal oscillator

• LIN-capable Enhanced Universal Synchronous/Asynchronous Receiver/Transmitter (EUSART)

• 12 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).
