Renesas DF2339EVFC25V

Overview

DF2339EVFC25V 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 10-bit ADCs (8+4 channels), four 16-bit timer pulse units (TPU), two SCIs, and DMA controller. It operates at up to 25 MHz and targets embedded control systems requiring reprogrammable firmware and mixed-signal integration.

For engineers reviewing the DF2339EVFC25V datasheet, DF2339EVFC25V pinout, DF2339EVFC25V application, or DF2339EVFC25V equivalent, key selection criteria include its 144-pin TFP package, 25 MHz max clock frequency, flash endurance of ≥100 write/erase cycles, 10-year data retention, and support for expanded bus mode with seven chip select outputs.

Technical Context

The DF2339EVFC25V implements the H8S/2000 32-bit internal architecture with 16-bit external data bus, supporting both single-chip and expanded modes. Its peripheral set includes a watchdog timer (WDT), D/A converter (2-channel, 8-bit), and programmable interrupt controller with 16 vectored IRQ inputs.

It features dual serial communication interfaces (SCI0/SCI1) supporting asynchronous and clock-synchronous modes, with baud rate generation via programmable bit rate registers. The on-chip flash memory supports in-system programming (ISP) and sector erase, enabling field firmware updates without external programmers.

FAQ

What is the maximum operating frequency of the DF2339EVFC25V?

The DF2339EVFC25V operates at a maximum clock frequency of 25 MHz. This rating is specified under standard conditions (3.0 V to 3.6 V supply, TA = –20°C to +75°C) and defines the upper limit for instruction execution speed, peripheral timing, and synchronous interface performance. The device achieves this frequency using an external crystal (XTAL/EXTAL) or external clock source, with internal PLL circuitry not present - so system clock equals input clock frequency.

Does the DF2339EVFC25V support in-system programming of its flash memory?

Yes, the DF2339EVFC25V supports in-system programming (ISP) of its 512 KB F-ZTAT™ flash memory. Programming and erasure can be performed via the on-chip debug interface using standard Renesas E8/E8a emulators or through user firmware executing flash command sequences. Each block erase takes 50–1000 ms, and the flash is rated for ≥100 write/erase cycles with 10-year data retention when operated within specification limits.

How many analog-to-digital converter channels does the DF2339EVFC25V provide?

The DF2339EVFC25V integrates two independent 10-bit successive approximation register (SAR) ADCs: one with 8 input channels (AN0–AN7) and another with 4 input channels (AN12–AN15). Channels AN14 and AN15 double as D/A outputs (DA2 and DA3), enabling mixed-signal functionality. Conversion time is 1.2 μs per sample, and the ADCs support software/start-triggered and external trigger modes.

What package type and pin count does the DF2339EVFC25V use?

The DF2339EVFC25V uses a 144-pin Thin Fine-Pitch Quad Flat Package (TFP), designated FP-144G, with 0.5 mm lead pitch and 20 mm × 20 mm body size. It includes an exposed thermal pad on the underside for improved heat dissipation. This package provides 112 general-purpose I/O pins, seven chip select outputs, and full access to all on-chip peripherals including dual SCIs, four TPUs, and dual ADCs.

Is the DF2339EVFC25V qualified for automotive applications?

No, the DF2339EVFC25V is classified as a "Standard" quality grade device per Renesas documentation and is intended for applications such as industrial automation, office equipment, and consumer electronics - not automotive or safety-critical systems. It is not AEC-Q100 qualified, lacks extended temperature range support (–40°C to +125°C), and does not undergo automotive-specific reliability testing. For automotive use, Renesas recommends the RH850 or RL78/F1x families instead of the H8S/2339 Group.
