Part of the vendor’s 16-bit H8S microcontroller series, the H8S/2153 and H8S/2164 microcontrollers provide 40 kbytes of RAM and 512 kbytes of flash memory. Aiming at advanced communications equipment, the H8S/2153 includes four unified-I2C-bus channels and an LPC bus. The device also includes an eight-channel, 10-bit ADC; an eight-channel event counter; and a data-transfer controller. Using a 34-MHz H8S/2600 microprocessor core with a built-in MAC (multiply/accumulate) function, the 3.3V H8S/2164 provides a 16550-compatible UART with a snoop option suiting baseboard-management-controller applications. The device also features six I2C-bus channels; an eight-channel, 10-bit ADC; a 16-channel event counter; a data-transfer controller; a bus-state controller; eight- and 16-bit timers; and a watchdog timer. The H8S/2153 and H8S/2164 microcontrollers come in 10×10-mm BGA-112 and 16×16-mm TQFP-144 packages, respectively, and each costs $15.
