SH7237

Description

The SH7239 Series is a high-end single chip microcontroller incorporating an SH-2A core that offers a maximum operating frequency of 160MHz. The SH7239 Series lineup consists of the SH7239 group (with floating-point unit (FPU)) and the SH7237 group (without FPU). The SH7237/SH7239 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) and a 12-bit A/D converter, etc.& In comparison with a conventional product, maximum operating frequency of MTU2 was improved. (3.3V version: max 80MHz, 5V version: max 100MHz) The SH7237/SH7239 group incorporates 512KB flash memory and 64KB RAM in addition to 32KB flash memory for data storage. The SH7237/SH7239 group also incorporates various interfaces such as a CAN, 4 channel Serial interface, RSPI etc.

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.

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.
