Microchip Expands 20-Pin PIC Microcontroller Family [Copy link]

Microchip Technology Inc. (Microchip Technology) recently announced the launch of two new 20-pin PIC? microcontrollers, further strengthening its 8-bit microcontroller series.

The PIC16F631 provides a cost-effective solution for 8-pin and 14-pin devices to 20-pin devices; while the PIC16F677 provides users in the small flash microcontroller market with reasonably priced hardware I2C? and SPI functions. Both devices are fully compatible with Microchip's latest mid-range architecture PIC microcontrollers, making them ideal for upward migration, thereby enriching the functionality and reducing the cost of existing 20-pin designs.

The new microcontrollers are an extension and extension of the PIC16F685/687/689/690 series, and can directly replace corresponding devices with more functions. Their board designs, control codes and tool kits can be reused without any modification, allowing engineers to break free from the constraints of additional costs and design platform-based systems more freely.

Both devices have the following features: nanoWatt technology to ensure the lowest power consumption in battery-driven applications; two analog comparators with S/R latch mode, eliminating the need for discrete devices; and In-Circuit Serial Programming technology (In-Circuit Serial Programming) for field programmability. Programming?). These feature improvements help simplify increasingly complex embedded control systems.

The new PIC16F631/677 microcontrollers are targeted at a diverse range of markets, including battery-powered equipment (security systems, smoke and carbon monoxide detectors and handheld devices), home appliances (electric frying pans, washing machines and dryers) and power conversion (power supplies, DC/DC converters and battery chargers).

Key features of the new PIC16F631/677 microcontrollers include:
Features shared by both devices
? Up to 3.5 KB of Flash program memory
? Up to 128 bytes of RAM memory
? A wide range of internal clock frequencies (31 kHz to 8 MHz)
? Two comparators with S/R latch mode
? 0.6V internal bandgap reference source
? Ultra-low power wake-up function
? Enhanced low-current watchdog timer
? Enhanced gated low-power timer1
? In-circuit serial programming technology
? Brown-out reset function with software control option
? Up to 18 input/output pins
? Space-saving 4x4 QFN package

PIC16F677 unique features
? 10-bit digital-to-analog converter (ADC) with 12 channels
? Supported by SPI and I2C with address masking options.

Microchip's full range of high-performance development tools supports these two new devices, including PICkit? 2 starter kit, free MPLAB? IDE (integrated new development environment) and low-cost MPLAB ICD 2 (in-circuit debugger).

PIC16F631 and PIC16F677 microcontrollers will provide samples and put into mass production in mid-July. Both products are lead-free devices that comply with RoHS and are available in 20-pin PDIP, SOIC, SSOP and QFN packages.
