Renesas DF2623FA20V

Overview

DF2623FA20V 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 in industrial equipment and office automation.

For engineers reviewing the DF2623FA20V datasheet, DF2623FA20V pinout, DF2623FA20V application, or DF2623FA20V equivalent, this page delivers verified technical identity, validated package mapping (LQFP-100), confirmed pin functions, real-time peripheral timing constraints, and two documented alternative microcontrollers for migration or sourcing continuity.

Technical Context

The DF2623FA20V 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 on-chip flash programming/erasing with SWE1-controlled write enable timing.

Its integrated HCAN module complies with ISO 11898-1 (CAN 2.0B), supports bit rates up to 1 Mbps, and features message buffering with priority arbitration. The TPU provides six 16-bit timer channels with input capture, output compare, PWM generation, and phase counting capabilities - all synchronized to a common clock source.

Key Specifications

FAQ

What is the maximum operating frequency of the DF2623FA20V?

The DF2623FA20V operates at a maximum CPU clock frequency of 20 MHz. This rating is guaranteed under specified voltage (3.0–5.5 V) and temperature (−40°C to +85°C) conditions per its datasheet. The internal PLL derives the bus clock from CLKIN, and timing-critical peripherals such as TPU and HCAN are synchronized to this clock domain. DF2623FA20V maintains full functionality and timing compliance only when operated within this frequency limit.

Does the DF2623FA20V include an integrated CAN transceiver?

No, the DF2623FA20V integrates the HCAN protocol controller (ISO 11898-1 compliant), but not the physical-layer transceiver. It provides CTX0/CRX0 differential signal outputs that require connection to an external CAN transceiver (e.g., SN65HVD230 or TJA1042) for bus termination, slew rate control, and ESD protection. DF2623FA20V handles message framing, arbitration, and error handling - the transceiver manages electrical signaling.

What flash programming method does the DF2623FA20V support?

The DF2623FA20V supports in-system programming (ISP) via its F-ZTAT™ flash technology. Programming and erasing are controlled through dedicated registers (e.g., SWE1 bit) and require precise timing sequences - including wait states after setting write-enable bits and prohibition windows during power transitions. DF2623FA20V does not require external high-voltage programming; all operations use standard VCC (3.0–5.5 V). Full details are in Section 19.13 of the Hardware Manual.

How many ADC channels does the DF2623FA20V provide, and what is their resolution?

The DF2623FA20V includes a 10-bit successive approximation register (SAR) ADC with 16 input channels. Conversion time is 1.2 µs per sample at maximum clock speed, and the module supports both software-triggered and timer-triggered sampling. DF2623FA20V's ADC integrates built-in offset calibration and selectable reference voltage sources (AVCC or internal bandgap), enabling accurate sensor measurements in noisy industrial environments.

Is the DF2623FA20V pin-compatible with other members of the H8S/2623 Group?

Yes, DF2623FA20V shares identical pinout and package (LQFP-100) with other H8S/2623 Group variants such as HD64F2623F20V and DF2623FA16V. Pin functions are consistent across these parts in Mode 4–7 configurations, allowing direct PCB reuse when migrating between flash/mask ROM versions or different speed grades. DF2623FA20V maintains full electrical and mechanical compatibility with these variants - no layout changes are needed for substitution within the same group.
