Product details
Overview
HD64F7052FJ40N from Renesas Technology Corp. is a 32-bit SuperH™ RISC microcontroller featuring the SH-2 CPU core, 512 KB on-chip flash memory, 32 KB RAM, and integrated peripherals including HCAN, SCI, DMAC, A/D converter, and PWM timers. It operates at 40 MHz with 3.3 V supply and targets real-time industrial control systems requiring reprogrammable firmware in-circuit.
For engineers reviewing the HD64F7052FJ40N datasheet, HD64F7052FJ40N pinout, HD64F7052FJ40N application, or HD64F7052FJ40N equivalent, key selection criteria include flash endurance (10,000 write/erase cycles), HCAN compliance (ISO 11898-1), 10-bit A/D resolution with 8-channel input, and F-ZTAT™ zero-turnaround-time external bus interface for deterministic memory access.
Technical Context
The HD64F7052FJ40N implements the SH-2 instruction set architecture with single-cycle execution for basic instructions, 32-bit internal data path, and Harvard-style memory architecture supporting separate instruction and data buses. Its CPG supports crystal or external clock inputs with programmable PLL multiplication to achieve stable 40 MHz operation.
Hardware exception handling includes 64-vector interrupt controller (INTC) with priority levels, user break controller (UBC) for debug breakpoints, and dual-address mode for 16-bit external memory interfacing requiring two bus cycles per access. The HCAN module provides full CAN 2.0B protocol support with message filtering and transmit/receive FIFOs.

FAQ
What is the maximum operating frequency of the HD64F7052FJ40N?
The HD64F7052FJ40N operates at a maximum CPU clock frequency of 40 MHz, achieved via its internal PLL that multiplies an external 4–20 MHz crystal or clock input. This frequency enables 40 MIPS throughput for real-time control tasks such as motor commutation and closed-loop feedback processing. The HD64F7052FJ40N maintains timing integrity across all on-chip peripherals-including A/D conversion, PWM generation, and HCAN transmission-at this rated speed.
Does the HD64F7052FJ40N support in-system programming of its flash memory?
Yes, the HD64F7052FJ40N supports in-system programming (ISP) of its 512 KB on-chip flash memory using standard programming tools compatible with the SH7052F family. Flash erase and write operations can be executed via software commands without removing the HD64F7052FJ40N from the target board, enabling field firmware updates and configuration changes. Programming endurance is specified at 10,000 cycles per block.
What peripheral interfaces are integrated into the HD64F7052FJ40N?
The HD64F7052FJ40N integrates a comprehensive set of peripherals: HCAN controller (ISO 11898-1 compliant), two independent SCI modules, 10-bit 8-channel A/D converter, four-channel DMAC, six 16-bit timers (including PWM-capable units), interrupt controller (INTC), user break controller (UBC), and bus state controller (BSC). These peripherals are tightly coupled to the SH-2 core and share memory-mapped registers accessible without external glue logic.
Is the HD64F7052FJ40N pin-compatible with other SH705xF series microcontrollers?
The HD64F7052FJ40N shares the same 208-pin FP-208A package and core pinout with HD64F7053FJ40 and HD64F7054FJ40, differing only in on-chip memory size and peripheral enablement. However, it is not pin-compatible with higher-flash variants like HD64F7055FJ40, which adds USB-related pins. Pin compatibility is limited to the SH7052F/7053F/7054F subgroup as defined in Renesas Hardware Manual ADE-602-185B.
What development tools are officially supported for the HD64F7052FJ40N?
Renesas officially supports the HEW (High-performance Embedded Workshop) IDE with C compiler and debugger, along with the E8/E8a in-circuit emulators for the HD64F7052FJ40N. Programming is supported via dedicated SH-family programmers such as the PG-FP5. The HD64F7052FJ40N also works with third-party JTAG adapters compliant with the SH-2 debug specification, though Renesas does not guarantee full feature support outside its validated toolchain.
