Low power rf SoC integrates dsp processor
CSEM has developed a SoC tailored for portable wireless communication products. It includes an integrated dsp processor and optimised power management.
The rf SoC integrates a 900MHz low power rf transceiver, a 32bit 150µA/MHz dual-MAC dsp risc core with 96kibytes of sram. Named icycom, the SoC runs off a 1V supply, compatible with a single alkaline cell, and is optimised for long battery life. According to CSEM, the device consumes 3.5mA in receiving active mode, 40mA for 10dBm transmission and 1.1µA in standby with RTC running.
Additional peripherals include a voltage divider, ADC, SPI, I2C, UART, and I2S on the same chip.
CSEM says that the icycom SoC could open up the way to ultra compact, autonomous wireless systems such as WSN, BAN and others.
