Renesas DF2623FA20JV

Overview

DF2623FA20JV from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2623 Group, featuring a 32-bit H8S/2600 CPU core, 256 KB on-chip flash memory (F-ZTAT™), 16 KB RAM, and integrated peripherals including TPU, SCI, HCAN, A/D converter, and DTC. It operates at up to 20 MHz and targets embedded control applications requiring deterministic real-time response and compact system integration.

For engineers reviewing the DF2623FA20JV datasheet, DF2623FA20JV pinout, DF2623FA20JV application, or DF2623FA20JV equivalent, this device is selected for industrial motor control, automotive body electronics, and factory automation systems where flash reprogrammability, CAN bus support, and low-power operation under 3.3 V supply are critical design requirements.

Technical Context

The DF2623FA20JV implements the H8S/2600 CPU core with sixteen 16-bit general-purpose registers (32-bit internal configuration), one-cycle basic instruction execution, and a 16 Mbyte linear address space. It supports boot-mode selection via MD2–MD0 pins and includes hardware reset circuitry with RES pin assertion timing defined for reliable power-on initialization.

On-chip peripherals include a 16-bit Timer Pulse Unit (TPU) with 8 channels, a 10-bit A/D converter with 8 input channels, a Controller Area Network (HCAN) module compliant with ISO 11898-1, and a Data Transfer Controller (DTC) enabling CPU-independent memory-to-peripheral transfers. Flash programming uses F-ZTAT™ technology with SWE1 bit-controlled write/erase enable.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the DF2623FA20JV?

The DF2623FA20JV operates at a maximum frequency of 20 MHz when supplied with 3.3 V ±0.3 V. This clock speed is specified under full industrial temperature range (−40°C to +85°C) and defines the upper limit for instruction execution rate, peripheral timing, and PWM carrier frequency generation. The DF2623FA20JV does not support overclocking beyond this rating.

Does the DF2623FA20JV include an integrated CAN controller?

Yes, the DF2623FA20JV integrates a hardware HCAN module compliant with ISO 11898-1. It supports standard and extended frame formats, has three transmit mailboxes and two receive mailboxes, and includes automatic retransmission and error confinement logic. The DF2623FA20JV requires an external CAN transceiver (e.g., TJA1040) for physical layer connection.

What type of flash memory is used in the DF2623FA20JV?

The DF2623FA20JV uses Renesas' proprietary F-ZTAT™ (Flexible-ZTAT) flash memory, offering 256 KB of on-chip, single-power-supply, reprogrammable non-volatile storage. This flash supports sector erase, byte programming, and secure boot mode configuration-all without requiring external high-voltage programming signals.

How much RAM does the DF2623FA20JV provide?

The DF2623FA20JV includes 16 KB of on-chip SRAM mapped into the internal address space. This RAM is used for stack, heap, global variables, and real-time data buffers. It is accessible at full CPU speed with zero wait states and supports byte, word, and long-word access modes as defined by the H8S/2600 architecture.

What is the function of the MD2–MD0 pins on the DF2623FA20JV?

The MD2–MD0 pins on the DF2623FA20JV are mode-select inputs sampled during reset release to determine boot source and initial memory mapping. They configure whether the DF2623FA20JV boots from on-chip ROM, flash memory, or user-defined vector table-enabling flexible production programming, field recovery, and debug workflows without hardware changes.
