Компания Renesas Technology America Inc начала выпуск двух новых приборов своего семейства 16-разрядных микроконтроллеров H8S - H8S/2164 и H8S/2153, которые предназначены для использования в серверах и высококачественном коммуникационном оборудовании. [англ.]
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, uTCA, and AMC management controllers. Both MCUs are based on the Renesas H8S CPU core and combine up to 34 MIPS performance with combinations of on-chip memory and peripheral functions.
The H8S/2164 has the speed and on-chip resources required to power a next-generation of server systems. The 3.3-volt 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: 40 kilobytes (40KB) of RAM and 512KB 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 I2C 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 I²C channels produce size and cost savings by eliminating the need for external converters. The MCU’s other on-chip functions include an 8-channel 10-bit A/D converter, 16-channel event counter (EVC), data transfer controller (DTC), bus-state controller (BSC), 8-bit and 16-bit timers, watchdog timer (WDT), and more.
The MCU is available in a compact (16×16 mm), 144-pin TQFP package that is pin-compatible with the H8S/2168 series.
The H8S/2153 is a reduced-size, high capability 16-bit microcontroller optimized for advanced ATCA, uTCA, and AMC management controllers in communication equipment. The 25MHz, 3.3V device has a 16-bit H8S/2600 CPU core with MAC. It provides 40KB of RAM, 512KB of flash memory, and the peripherals required for target applications. Those on-chip functions include four unified channels of I²C bus and an LPC bus for connections to external peripheral systems.
The MCU has an 8-channel 10-bit A/D converter, 8-channel EVC, DTC, timers and more. The chip is packaged in a 10mm x 10mm, 112-pin BGA.
