New Renesas H8SX 50MHz 32Bit Microcontrollers Announced

Share:

Renesas Technology America, Inc. today introduced the new 32-bit H8SX/1653F and H8SX/1651 microcontrollers running at 50MHz.

The new devices target designs of PC peripherals, office equipment, consumer electronics products, industrial systems, POS (Point-of-Sale) and smart card payment terminals.

The new Renesas H8SX series was launched last year with the Renesas H8SX/1650 and H8SX/1657F, 35MHz devices optimized for consumer electronics products. Besides being almost 43 percent faster, the new 50MHz microcontrollers provide an expanded set of on-chip peripheral functions.The serial communication interface (SCI) which supports both asynchronous and clock-synchronous data transfers, has been increased to five channels in the H8SX/1651 and six channels in the H8SX/1653F. The H8SX/1653F also includes two channels that support high-speed asynchronous serial data transfers and has a USB 2.0 (full speed) function. Both microcontrollers incorporate an on-chip, JTAG-compliant debugger interface.

The Renesas H8SX/1651 and H8SX/1653F also support a smart card interface as an asynchronous mode extension. This makes it possible to implement highly tamper resistant POS terminals or smart card payment terminals by combining either device with a Renesas AE-series smart card microcontroller.

The H8SX/1653F has 384-KByte of on-chip flash memory that can be accessed in a single cycle, even at the full 50MHz clock speed, for the fastest possible program execution.

The H8SX/1651 has no internal flash or ROM and requires external program memory. A boot function for writing program data to external ROM allows programs to be rewritten after the ROMless H8SX/1651 is mounted on a circuit board.

Both microcontrollers have 40 KBytes of on-chip RAM.

New development tools for the Renesas H8SX microcontrollers include the E6000H full emulator, E10A-USB compact on-chip emulator, and the Embedded Workshop, an integrated development environment with C/C++ compiler, editor, etc. Third party tools are also available.
