PIC18F87J72 High-Performance Microcontrollers

Microchip's PIC18F87J72 for single-phase, multi-function smart-metering and energy-monitoring applications

Microchip PIC18F87J72 High-Performance Microcontrollers Microchip announces an 8-bit PIC18F87J72 MCU family for single-phase, multi-function smart-metering and energy-monitoring applications. Featuring a dual-channel, high-performance 16-/24-bit AFE, the new MCUs provide an accurate, reliable, easy-to-use, and cost-effective solution for developing meters that exceed International Electrotechnical Commission (IEC) class 0.5 performance standards. The family includes 64 or 128kB Flash program memory and 4kB RAM to enable time-of-use and multi-tariff functions as well as a high level of peripheral integration, including an LCD driver, hardware Real-Time Clock/Calendar (RTCC) and a Charge-Time Measurement Unit (CTMU) that enables a capacitive-touch user interface. Energy-calculation firmware, a development board and a reference design are available, providing a complete solution that lowers costs and shortens time to market for smart-metering and energy-monitoring applications.

  • Dual-channel 16-/24-bit AFE with Delta-Sigma A/D converters and high-gain PGAs for 90dB SINAD and -101dBc THD (to 35th harmonic) performance
  • 12-bit, 12-channel, 100ksps SAR A/D converter
  • LCD driver for up to 132 pixels with voltage boost regulator
  • Hardware real-time clock & calendar
  • Charge Time Measurement Unit (CTMU) for temperature sensing and capacitive touch
  • Two analog comparators
  • Two UARTs
  • One Master Synchronous Serial Port (MSSP) support SPI™ and I2C™
  • Four timers
  • Two Capture/Compare/PWM (CCP)
  • Up to 12MIPS performance
  • RoHS Compliant
  • Internal oscillator support 31kHz to 8MHz and 4xPLL
  • 8x8 single cycle hardware multiply
  • nanoWatt low power with run, idle and sleep modes
  • Brown-Out-Reset (BOR)
  • Low Voltage Detect (LVD)
  • Operating voltage range: 2.0V to 3.6V for digital and 12-bit ADC; 4.5V to 5.5V for 16-/24-bit AFE
