MICROCHIP Technology Australia Pty Ltd , a leading provider of microcontroller and analog semiconductors, has announced two new 20-pin PIC microcontrollers to further strengthen its 8-bit portfolio.

The PIC16F631 provides a cost-effective entry point for migration from 8- and 14-pin devices, while the PIC16F677 brings affordable hardware I2C and SPI capability to the small Flash microcontroller market.

Full compatibility with Microchip's latest midrange architecture PIC microcontrollers also makes the pair an excellent choice for upward migration to add more functionality or cost reduction of existing 20-pin designs.

The new microcontrollers are an extension of the PIC16F685/687/689/690 series, and can be used as "drop-in" replacements for their more feature-rich counterparts.

Board layout, control code, and tool suites can be completely re-used without modification-giving engineers the freedom to design platform-based systems without the associated cost penalty.

Both devices employ the following features: nanoWatt Technology for minimum power consumption in battery-powered applications; dual analog comparators with S/R latch mode to eliminate the need for discrete components; and In-Circuit Serial Programming technology for field programmability.

These enhancements serve to simplify the design of increasingly complex embedded-control systems.

The new PIC16F631/677 microcontrollers serve a broad market, including the following example applications: battery-powered devices (security systems, smoke and CO detectors, handheld devices), appliances (deep fryers, washers, dryers), and power conversion (power supplies, DC/DC converters, battery chargers).

The two new devices are supported by the full suite of Microchip's development tools, including the PICkit 2 Starter Kit, free MPLAB IDE (Integrated Development Environment), and the low-cost MPLAB ICD 2 (In-Circuit Debugger).

The PIC16F631 and PIC16F677 microcontrollers are available now for general sampling in RoHS-compliant 20-pin PDIP, SOIC, SSOP and QFN packages

Microchip is committed to supporting its customers by helping design engineers develop products faster and more efficiently.
