16-bit MCU family keeps power low

Chips take 1 µA in standby and have up to 64 Kbytes of flash

The 78K0R/Kx3-L series of 16-bit MCUs is said to have Industry-leading low-power consumption. The chips offer 1.5 mW per Dhrystone 1.1 MIPS and more on-chip integration to help reduce the size and cost of battery-driven and sensor-enabled systems such as fire and security alarms, meters, industrial sensors, digital cameras, handheld medical diagnostics devices, and data-logging and point-of-sale terminals.

By optimizing power management, device standby power has been reduced by 60% from an average of 2.4 µA to 1.0 µA. At a clock speed of 10 MHz, power has been reduced by 10%, from 3.9 to 3.5 mA, and at 20 MHz by 20%, from 8.2 to 6.5 mA. The chips have a 12-channel, 3-µs, 10-bit A/D converter, up to 64 Kbytes of flash, and 44 to 64-pin packages as small as 5 x 5 mm.

They have three oscillator circuits producing ±1% accuracy operating frequencies. (With 4 Kbytes of flash, 64-pin FPBGA package, $4.50 — available August.)
