MCU with On-Chip Flash Memory Built with a 90 nm Process
Renesas added a microcontroller (MCU) to its32-bit SuperH family: the SH72546RFCC, said to be the industry's first MCU with on-chip flash memory built with a 90-nm (nanometer) process node. The device is optimized for the development of control programs for automobile engines, transmissions, and other systems that require real-time control capabilities. It achieves an operating speed of 200 MHz in the high-temperature environment (up to 125°C) required for automotive applications. In addition, the device's on-chip flash memory capacity is among the largest currently offered --3.75 Mbytes -- enough to store cutting-edge high-precision real-time control algorithms. The SH72546RFCC (FCC = flash on-chip calibration chip) device is a preproduction device optimized for control program development, offering a set of features tailored to aid software design and debug. It forms the basis for an upcoming mass-production product family that will have performance, package, and pin arrangement compatibility. Engineers performing system development using the SH72546RFCC will be able to transition to lower-cost mass production devices.
