Microchip Technology introduced the 8-bit PIC18F87J72 microcontroller (MCU) family. The PIC18F87J72 microcontrollers feature a dual-channel 16-/24-bit Analog Front End (AFE), 64 or 128 KB Flash program memory, 4 KB RAM, LCD driver, hardware Real-Time Clock/Calendar (RTCC), and a Charge-Time Measurement Unit (CTMU). The new Microchip MCU devices are ideal for single-phase, multi-function smart-metering and energy-monitoring applications. The PIC18F87J72 is available now for $3.93 each in 10,000-unit quantities for 64 KB Flash program memory.
Microchip Technology introduced the MCP3901 Analog Front End (AFE) for metering applications. The MCP3901 AFE features high-accuracy, dual 16-/24-bit Delta-Sigma Analog-to-Digital Converters (ADCs) with up to 91 dB Signal to Noise and Distortion (SINAD), internal Programmable Gain Amplifiers (PGAs) and voltage reference, phase-delay compensation, and a modulator output block that enables more precise measurements than competitive solutions. The MCP3901 AFE is available in a 20-pin SSOP package, for $1.42 each in 10,000-unit quantities.
