PIC18F87J72 High-Performance Microcontrollers

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

Microchip Technology's PIC18F87J72 High-Performance MicrocontrollersMicrochip 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 128 kB Flash program memory and 4 kB 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.

Features
  • Dual-channel 16-/24-bit AFE with Delta-Sigma A/D converters and high-gain PGAs for 90 dB SINAD and -101 dBc THD (to 35th harmonic) performance
  • 12-bit, 12-channel, 100 ksps SAR A/D converter
  • LCD driver for up to 132 pixels with voltage boost regulator
  • Hardware RTCC
  • CTMU for temperature sensing and capacitive touch
  • Two analog comparators
  • One master synchronous serial port (MSSP) supports SPI™ and I2C™
  • Two UARTs
  • Four timers
  • Two capture/compare/PWM (CCP)
  • Up to 12 MIPS performance
  • Internal oscillator support 31 kHz to 8 Hz and 4xPLL
  • 8 x 8 single-cycle hardware multiply
  • nanoWatt low power with run, idle, and sleep modes
  • Brown-out-reset (BOR)
  • Low-voltage detect (LVD)
  • Operating voltage range: 2.0 V to 3.6 V for digital and 12-bit ADC; 4.5 V to 5.5 V for 16-/24-bit AFE
