Infotainment Applications

Microchip Technology Infotainment Applications include everything from re-routing due to traffic delays, to providing intuitive visual, auditory, and tactile interfaces. This includes interfaces to the vehicle's distributed and networked subsystems like air conditioning, drivetrain, and body controls. Browse and access a host of media and content or catch up on social media through the onboard connectivity options.

Real-Time Clocks

Microchip Real-Time Clocks are offered from basic low-cost devices to various mid-range devices. These highly integrated devices have a usable amount of non-volatile memory and a combination of features that are very effective when operating within a single battery-backed clock device. With I2C and SPI RTCCs, various applications can be supported with fewer features and lower performance.

Clock and Timing Solutions

Microchip Clock and Timing Solutions are an extensive clock and timing product portfolio for complex timing requirements in designs. Microchip's oscillator products offer low jitter and low power with quartz- or MEMS-based resonators. The clock generation line offers online configurability, single-chip and multiple-frequency clock tree solutions. The clock and data distribution product line includes buffers, logic translators and multiplexers.

MCP7940N Real-Time Clock/Calendar (RTCC)

Microchip Technology MCP7940N Real-Time Clock/Calendar (RTCC) uses digital timing compensation for an accurate clock/calendar, a programmable output control for versatility, and a power sense circuit that automatically switches to the backup supply. Using a low-cost 32.768kHz crystal, it tracks time using several internal registers. For communication, the MCP7940N uses the I2C bus. The clock/calendar automatically adjusts for months with fewer than 31 days, including corrections for leap years. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator and settable alarm(s) to the second, minute, hour, or day of the week, date, or month. Using the programmable CLKOUT, frequencies of 32.768kHz, 8.192kHz and 4.096kHz and 1Hz can be generated from the external crystal. The device is fully accessible through the serial interface while VCC is between 1.8V and 5.5V, but can operate down to 1.3V for timekeeping and SRAM retention only.
