Renesas Technology America Inc. has added two devices to its H8S series of 16bit MCUs: the H8S/2164 and H8S/2153, which are tailored for use in servers and advanced communication equipment.

The H8S/2164 device is a second-generation device aimed at baseboard management controller (BMC) applications, while the H8S/2153 is ideal for communications equipment such as ATCA, ?TCA and AMC management controllers. Both MCUs are based on the Renesas H8S CPU core and combine up to 34MIPS performance with combinations of on-chip memory and peripheral functions.

Smart solution
The H8S/2164 has the speed and on-chip resources required to power a next-generation of server systems. The 3.3V device has a 34MHz H8S/2600 CPU core with a built-in multiply-accumulate (MAC) function, and integrates the large amounts of on-chip memory needed for robust and flexible communications systems: 40Kbytes of RAM and 512Kbyte of flash memory. Built-in peripheral functions include an industry-standard 16550-compatible UART with a snoop option that allows connections to a wide variety of external peripheral systems.

The device has six IC unified channels that allow direct connections to the management infrastructures used for the efficient sharing and processing of data with other parts of communication systems. The I?C channels produce size and cost savings by eliminating the need for external converters. The MCU's other on-chip functions include an 8-channel 10bit ADC, 16-channel event counter (EVC), data transfer controller (DTC), bus-state controller (BSC), 8bit and 16bit timers, watchdog timer (WDT) and more.

The MCU is available in a compact (16mm x 16mm), 144-pin TQFP package that is pin-compatible with the H8S/2168 series.

The H8S/2153 is a reduced-size, high capability 16bit MCU optimized for advanced ATCA, ?TCA, and AMC management controllers in communication equipment. The 25MHz, 3.3V device has a 16bit H8S/2600 CPU core with MAC. It provides 40Kbyte of RAM, 512Kbyte of flash memory and the peripherals required for target applications. Those on-chip functions include four unified channels of I�C bus and an LPC bus for connections to external peripheral systems.

The MCU has an 8-channel 10bit ADC, 8-channel EVC, DTC, timers and more. The chip is packaged in a 10mm x 10mm, 112-pin BGA.
