Microchip Unveils PIC16F145X, PIC18F2X/4XK50 and PIC18F97J94 Microcontrollers

Microchip Technology PIC16F145X, PIC18F2X/4XK50 and PIC18F97J94 microcontrollers

Microchip Technology launched the PIC16F145X, PIC18F2X/4XK50 and PIC18F97J94 microcontrollers. The new MCU families consist of 15 scalable MCUs ranging from 14 to 100 pins with up to 128 KB of Flash. The devices feature internal clock sources with the 0.25% clock accuracy necessary for USB communication, which saves up to $0.15 by eliminating the need for an external crystal. In addition, all three families are eXtreme Low Power compliant, with power consumption down to 35 µA/MHz Active and 20 nA in Sleep mode.

Microchip MCP794XX Real-Time Clock/Calendar IC Family

Microchip Technology introduced their MCP794XX stand-alone I2C Real-Time Clock/Calendar (RTCC) family. The MCP794XX features on-chip EEPROM and SRAM, digital trimming for time-of-day calibration, battery-switchover, user-lockable section of EEPROM, 64-bit reprogrammable unique ID that can be factory-programmed with a MAC address. All six MCP794XX RTCC devices are available in 8-pin MSOP, SOIC, TSSOP and TDFN packages. The MCP79400 is priced at $0.64 each; the MCP79401, MCP79402 and MCP79410 at $0.70 each; and the MCP79411 and MCP79412 at $0.76 each, all in 10,000-unit quantities. The devices are ideal for smart-energy (thermostats, power meters and commercial refrigeration), home-appliance (stoves, dishwashers and microwave ovens), automotive (dashboard controls and car radios), and consumer-electronic markets (office equipment, irrigation controls and video systems).
