Product details
Overview
HD6472655RTEV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2655 Group, featuring a 32-bit H8S/2600 CPU core, 512 KB on-chip mask ROM, 32 KB RAM, and integrated peripherals including TPU, SCI, A/D converter, D/A converter, DMA controller, and watchdog timer. It operates at up to 33 MHz and targets industrial control systems requiring deterministic real-time response.
For engineers reviewing the HD6472655RTEV datasheet, HD6472655RTEV pinout, HD6472655RTEV application, or HD6472655RTEV equivalent, key selection criteria include its 120-pin TFP package, 16-channel 16-bit timer pulse unit, 8-channel 10-bit A/D converter with 1.2 µs conversion time, and support for asynchronous serial communication via two SCI modules.
Technical Context
The HD6472655RTEV implements the H8S/2600 CPU core with sixteen 16-bit general-purpose registers (32-bit internal width), one-cycle basic instruction execution, and a 16-Mbyte linear address space. It supports eight configurable memory areas with selectable data bus width (8/16-bit) and wait-state control for flexible external memory interfacing.
On-chip peripherals include a 16-bit Timer Pulse Unit (TPU) with input capture, output compare, PWM generation, and phase counting modes; two independent Serial Communication Interfaces (SCI) supporting asynchronous mode with programmable baud rates; and an 8-channel, 10-bit successive-approximation A/D converter with internal reference voltage and sample-and-hold circuitry.

FAQ
What is the maximum operating frequency of the HD6472655RTEV?
The HD6472655RTEV operates at a maximum CPU frequency of 33 MHz, achieved via an internal PLL that multiplies an external crystal or clock input. This frequency enables sub-100 µs instruction execution for time-critical control loops. The HD6472655RTEV maintains timing consistency across temperature ranges from –40°C to +85°C, as verified in Renesas' published AC characteristics table.
Does the HD6472655RTEV include on-chip analog-to-digital conversion capability?
Yes, the HD6472655RTEV integrates an 8-channel, 10-bit successive-approximation A/D converter with a typical conversion time of 1.2 µs and an internal 2.5 V reference voltage. Channels AD0–AD7 are multiplexed with port pins and support software or TPU-triggered sampling. The HD6472655RTEV's A/D module is fully documented in Section 16 of the H8S/2655 Hardware Manual Rev. 5.00.
What package type is used for the HD6472655RTEV?
The HD6472655RTEV is packaged in a 120-pin Thin Fine-Pitch Plastic QFP (TFP-120) with 0.4 mm lead pitch and exposed thermal pad. This package is specified in Appendix G of the H8S/2655 Hardware Manual and complies with JEDEC MO-220. The HD6472655RTEV's pin layout supports high-density routing while maintaining signal integrity for mixed-signal operation.
How many serial communication interfaces does the HD6472655RTEV support?
The HD6472655RTEV includes two independent Serial Communication Interface (SCI) modules, each supporting asynchronous communication with programmable baud rates up to 1 Mbps. Both SCIs feature framing error detection, overrun error flags, and separate TXD/RXD pins. This dual-SCI capability allows the HD6472655RTEV to simultaneously handle protocol stacks such as Modbus RTU and proprietary diagnostics.
Is the HD6472655RTEV pin-compatible with other members of the H8S/2655 Group?
The HD6472655RTEV shares the same 120-pin TFP package and core peripheral set with other H8S/2655 variants like HD6432655 and HD64F2655FV, but pin assignments for specific functions (e.g., A/D inputs, TPU channels) differ across mask ROM, flash, and PROM versions. The HD6472655RTEV's exact pin mapping is defined in Section 1.3.3 of the H8S/2655 Hardware Manual and must be verified per variant before PCB reuse.
