Overview
DF2339VFC25V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2339 Group, featuring an H8S/2000 CPU core, 512 KB on-chip flash memory (F-ZTAT™), 32 KB RAM, and integrated peripherals including dual 16-bit timer pulse units (TPU), watchdog timer (WDT), SCI serial interfaces, A/D and D/A converters, DMA controller, and bus controller. It targets embedded control systems requiring deterministic real-time response, such as industrial motor drives and HVAC controllers.
For engineers reviewing the DF2339VFC25V datasheet, DF2339VFC25V pinout, DF2339VFC25V application, or DF2339VFC25V equivalent, key selection criteria include its 25 MHz max operating frequency, 144-pin TFP package with multiplexed address/data bus, flash reprogrammability (≥100 cycles), and support for expanded memory mode via CS0–CS7 chip select outputs.
Technical Context
The DF2339VFC25V implements the H8S/2000 32-bit internal architecture with 16-bit external data bus, supporting both minimum and expanded modes. Its memory interface includes programmable wait-state generation, asynchronous/synchronous bus timing control, and dedicated chip select signals (CS0–CS7) configurable via DDR and enable bits.
Peripheral integration centers on real-time control: two independent 16-bit TPUs with input capture/output compare capabilities, four-channel 10-bit A/D converter with external trigger support, dual-channel 8-bit D/A converter, and three full-duplex SCIs with baud rate generator and framing error detection - all accessible via memory-mapped I/O registers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2339 | Same core and peripheral set but in 128-pin PQFP package; lacks P56/P57 DAC functionality and has reduced A/D channel count (8 vs. 16). | Suitable for cost-sensitive designs where DAC integration is unnecessary and board space allows larger footprint. | Select HD64F2339 only if DAC channels and full 16-channel A/D are not required; verify pin compatibility for existing layouts. |
| R5F52338 | Successor RH850/F1L device with 32-bit CPU, 1 MB flash, enhanced CAN FD and Ethernet MAC; no pin or software compatibility with DF2339VFC25V. | Targeted at next-generation automotive body control modules requiring functional safety (ISO 26262) and network connectivity. | R5F52338 is not a drop-in replacement; migration requires full hardware redesign and software re-architecture. |
Compared with HD64F2339, DF2339VFC25V adds two DAC outputs and eight additional A/D channels in a denser 144-pin TFP package; compared with R5F52338, it offers lower cost and simpler toolchain for legacy industrial applications but lacks modern automotive interfaces and safety features.

FAQ
What is the maximum operating frequency of the DF2339VFC25V?
The DF2339VFC25V operates at a maximum frequency of 25 MHz, achieved using an external crystal (XTAL/EXTAL) or oscillator input. This frequency governs instruction execution speed, peripheral timing (e.g., SCI baud rates, TPU resolution), and A/D conversion sampling rate. The device supports programmable wait states to accommodate slower external memory or peripherals without reducing CPU clock speed.
Does the DF2339VFC25V support in-system programming of its flash memory?
Yes, the DF2339VFC25V supports in-system programming (ISP) of its 512 KB F-ZTAT™ flash memory via on-chip boot ROM routines accessible through SCI or dedicated programming mode. Reprogramming requires no external programmer; it supports ≥100 write/erase cycles with guaranteed 10-year data retention under specified operating conditions, making it suitable for field firmware updates in deployed equipment.
How many analog-to-digital converter channels does the DF2339VFC25V provide?
The DF2339VFC25V integrates a 10-bit successive approximation register (SAR) A/D converter with 16 input channels (AN0–AN15). Channels AN6/AN7 and AN14/AN15 are shared with DAC outputs (DA0–DA3), requiring software configuration to assign pin function. Conversion is triggered internally or externally (via ADTRG pin), supporting both continuous and single-shot modes for flexible sensor acquisition.
What package type and pin count does the DF2339VFC25V use?
The DF2339VFC25V uses a 144-pin Thin Fine-Pitch Quad Flat Package (TFP-144G) with 0.5 mm lead pitch and 20 mm × 20 mm body size. This package supports high I/O density for expanded memory interfaces (address/data multiplexing), multiple peripheral functions, and industrial-grade thermal dissipation. Pin assignments follow the standard H8S/2339 Group layout documented in Renesas Hardware Manual Rev.4.00.
Can the DF2339VFC25V interface directly with external DRAM?
Yes, the DF2339VFC25V supports direct DRAM interfacing via its PG0/CAS pin and programmable CS0–CS7 outputs. In expanded mode, it generates DRAM-specific control signals including column address strobe (CAS), row address strobe (RAS), and write enable (WE), with timing parameters configurable through system control registers. External DRAM must comply with the device's access timing specifications, particularly tRC and tRP minima.
