SH7231

Description

The SH7231 series is a high-end single chip microcontroller incorporating the SH-2A core and FPU. SH7231 operates at max 100MHz. The SH7231 series incorporates 1MB flash memory, 32KB RAM (for high speed access) and 12KB RAM( for data retention). The SH7231 group also incorporates various communication interfaces such as a CAN, SCI, SCIF, RSPI, LVDS receiver I/F etc. As others function, the SH7231 group incorporates various peripheral function suitable for industrial application AC servos, general-purpose inverters and robots, such as a 16-bit multifunction timer unit (MTU2/MTU2S) , a 10-bit A/D converter, and key scan controller (KEYC) that be able to control the key of max 80 input. SH7231 supports the deep-software-standby-mode suitable for machinery to drive with battery. KEYC and TIM32C can be working at deep software standby mode, and the datas of 12KB RAM (for data retention) are able to keep at deep software standby mode.

RX Family, SH Family, H8SX Family Points of Difference between RCAN-ET (SH Family, H8SXFamily) and CAN (RX Family) Rev.1.00
PDF 361 KB R01AN4767EJ0100 Rev.1.00 日本語 Sep 30, 2019
AI-generated Summary: The document details functional differences between RCAN-ET (SH and H8SX Families) and CAN (RX Family) controllers. It compares protocol compatibility, bit rates, channel numbers, mailbox configurations, ID formats, and transmission/reception capabilities. Key distinctions include FIFO mailbox support, message priority handling, interrupt types, error handling, and bus-off recovery. The RX65N supports more channels, FIFO modes, and additional interrupts, while SH7137 offers ID reordering and overwrite modes. These differences impact CAN communication performance and error management.

RX Development Environment Migration Guide Migration from SuperH Family to RX Family (IDE ed.) (High-performance Embedded Workshop to CS+)
PDF 1007 KB REJ06J0102-0200 Rev.2.00 日本語 Apr 20, 2017
AI-generated Summary: The document explains key compiler option differences when migrating source code from the SuperH family to the RX family. It highlights that char types default to signed in SuperH but unsigned in RX, requiring the 'signed_char' option to maintain behavior. It also covers the 'auto_enum' option for automatic enum size selection and the 'dbl_size' option to specify double type size, which defaults to 4 bytes in RX compared to 8 bytes in H8 compilers. Configuration steps in the CS+ IDE are provided for each option.

AI-generated Summary: The document explains how to register and uninstall Call Walker within the High-performance Embedded Workshop (HEW). It guides users to launch HEW without opening a workspace, access the Tools Administration menu, and register the Call Walker tool by specifying the registration file path. After registration, Call Walker version 2.3 appears in the menu. Upon uninstalling HEW, users must manually delete the remaining Call Walker directory. It also provides Renesas Electronics website and contact information for support. The revision history notes the first edition release date.

SH-2A Open Source FAT File System M3S-TFAT-Tiny: Introduction Guide
PDF 252 KB R20AN0190EJ0101 Rev.1.01 日本語 Nov 08, 2013
AI-generated Summary: The TFAT library supports FAT12, FAT16, and FAT32 file systems with 8.3 filename format and one drive. It is based on Fatfs (RO.06) and does not support long file names or filesystem formatting. The software stack includes the FAT file system, TFAT library, and device drivers. Development uses High-performance Embedded Workshop and SuperH C/C++ compiler. Compiler options for SH-2A and SH2A-FPU are specified. Version 2.00 is available for both CPU types. The library requires about 8.4KB ROM, 6 bytes RAM, and varying stack sizes depending on API functions. Memory allocation depends on the number of open files and directory structures.
