Microchip Further Expands Stand-Alone Real-Time Clock Calendar Device Family
Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of microcontroller, analog and Flash-IP solutions, today announced the expansion of its stand-alone Real-Time Clock Calendar (RTCC) family with the I2C™ MCP7940M RTCC device. This new device is designed for the price-competitive consumer products market, and includes 64 Bytes of SRAM as additional scratchpad memory, as well as a digital-trimming circuit that can compensate up to 11 seconds per day for crystal error. The MCP7940M devices provide accurate timekeeping at a low cost for applications in the home-appliance (e.g., microwaves, washing machines, dryers, ovens, thermostats); audio/video (e.g., radios, televisions, set-top boxes, digital recorders); and consumer-electronic markets (e.g., printers, network routers, cameras), among others.
Following the launches of Microchip's stand-alone I2C MCP79410 and SPI MCP795WXX/BXX RTCC devices in 2010 and 2011, respectively, the MCP7940M device has a simple feature set that meets the needs of the high-volume segment of the RTCC device market. Microchip now has stand-alone RTCC devices for the low, mid and upper-mid ranges of this market. The on-chip digital trimming circuit has a wide trimming range of +/-127 ppm, enabling designers to select lower-quality crystals for their designs to reduce overall system costs.
“After receiving many customer requests for low-end real-time clocks and conducting our own analysis of this market, we developed the MCP7940M RTCC device,” said Randy Drwinga, vice president of Microchip's Memory Products Division. “By offering a price-competitive RTCC that also includes 64 Bytes of SRAM and a digital-trimming circuit for higher accuracy, we believe that our solution will have a distinct advantage over the competition.”
Microchip's MCP79410 RTCC PICtail™ Plus Daughter Board (part # AC164140, $45) is available, today. The board works with Microchip's Explorer 16 Development Board (part # DM240001, $129.99), PIC18 Explorer Board (part # DM183032, $99.99), PICkit™ Serial Analyzer (part # DV164122, $49.99), and XLP 16-bit Development Board (part # DM240311, $59.99).
Packaging, Pricing & Availability
The MCP7940M RTCC is available today in 8-pin MSOP, PDIP, SOIC, TSSOP and 2 mm x 3 mm TDFN packages. Pricing starts at $0.45 each, in 10,000-unit quantities.
