Memory microcontrollers

Renesas has released the SH7216 group of 32-bit on-chip flash memory microcontrollers, the latest addition to the 32-bit SuperH RISC family.

It features 200 MHz operation and a set of built-in peripheral and communication functions for industrial applications such as AC servos, factory automation equipment, building automation and various types of communication apparatus.

The group consists of 36 devices in 12 product groups that differ in on-chip memory capacity, package type, and whether or not floating point processing unit and/or ethernet functions are included.

The main features are: operating speed of 200 MHz and an on-chip single-cycle access RAM that provides processing performance increased to 480 MIPS when the program is loaded into this memory.

The devices adopt the SH2A-FPU core, which includes an FPU that operates at up to control performance allowing the maintainability and performance of motor vector calculations and filter calculation and contributes to improved processing performance in factory automation and other industrial equipment and OA equipment as well.

In addition to the earlier serial communication functions, the microcontrollers also feature ethernet, CAN and USB2.0, full speed.

The devices provide two PWM timers (MTU2 and MTU2S) that can generate dead time and implement multi-axis motor control and servo motor control applications that require high precision.

They also provide 12-bit A/D converters that can perform conversions in 1 µs to improve precision and accuracy in motor control and other applications.

Other peripheral functions include data transfer controller and DMAC functions to reduce the CPU load and data storage flash memory that holds status information when power is not applied.
