Product details
Overview
DF2239FA16V from Renesas Electronics is a 16-bit flash-based microcontroller in the H8S/2239 Group, featuring an H8S/2000 CPU core, 512 KB on-chip flash memory, 32 KB RAM, six 16-bit timer pulse units (TPU), four 8-bit timers (TMR), dual watchdog timers (WDT), and four serial communication interfaces (SCI). It operates at up to 33 MHz and targets industrial control and embedded automation systems requiring deterministic real-time response.
For engineers reviewing the DF2239FA16V datasheet, DF2239FA16V pinout, DF2239FA16V application, or DF2239FA16V equivalent, key selection criteria include its 100-pin TFP-100BV package, flash reprogrammability in-system, integrated I²C option, 8-channel 10-bit A/D converter with sample-and-hold, and support for multiple low-power modes including subactive and deep standby.
Technical Context
The DF2239FA16V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, enabling efficient execution of complex control algorithms while maintaining compatibility with legacy H8 toolchains. Its peripheral set includes a bus controller (BSC) supporting external memory expansion, data transfer controller (DTC) for zero-CPU-overhead DMA-like transfers, and dual PC break controllers for precise debugging breakpoints.
It supports five operating modes - high-speed, fast, low-speed, subactive, and deep standby - controlled via software and hardware signals, with power consumption as low as 0.5 µA in deep standby. The device integrates two D/A converters (8-bit), eight analog input channels with configurable sampling timing, and IEBus™ controller support for legacy automotive equipment communication.

Pinout & Package
DF2239FA16V is housed in a 100-pin Thin Fine-Pitch Plastic Ball Grid Array (TFP-100BV) package with 0.5 mm pitch, optimized for compact industrial PCB layouts and thermal dissipation in enclosed enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2239FV | Same H8S/2239 core, identical 100-pin FP-100BV package, but uses standard plastic QFP instead of fine-pitch BGA; lacks TFP-100BV's thermal performance. | Better suited for prototyping or cost-sensitive designs where PCB assembly infrastructure doesn't support 0.5 mm pitch BGA. | Select HD64F2239FV when BGA rework capability is unavailable or thermal load is moderate. |
| R5F52239ADFP | RX220-series successor: 32-bit RXv1 core, 128 KB flash, 16 KB RAM, higher clock (50 MHz), enhanced peripheral set (USB, CAN), but no IEBus or F-ZTAT™ flash. | Targets next-generation designs requiring USB host/device, CAN FD, or larger code footprint; not drop-in compatible due to pinout and register map changes. | Choose R5F52239ADFP for new designs needing modern peripherals and scalability beyond H8S limitations. |
Compared with HD64F2239FV, DF2239FA16V offers superior thermal dissipation and higher I/O density in the same footprint; versus R5F52239ADFP, it retains legacy IEBus and flash-programming simplicity at the cost of 32-bit performance and modern interface support.

FAQ
What is the maximum operating frequency of the DF2239FA16V?
The DF2239FA16V operates at a maximum system clock frequency of 33 MHz, delivering 33 MIPS performance with single-cycle instruction execution. This frequency is supported across the full industrial temperature range (−40°C to +85°C) under 3.0–3.6 V supply conditions. The device uses an on-chip PLL to multiply external crystal or oscillator inputs, and timing margins are validated per Renesas' Electrical Characteristics table in the H8S/2239 Hardware Manual Rev. 6.00.
Does the DF2239FA16V support in-system programming of its flash memory?
Yes, the DF2239FA16V supports full in-system programming (ISP) of its 512 KB on-chip flash memory using the F-ZTAT™ technology. Programming can be performed via on-chip boot ROM routines triggered by specific pin states at reset, enabling field firmware updates without external programmers. The DF2239FA16V flash supports sector erase, byte/word programming, and read-while-write capability as documented in Section 9.2 of the H8S/2239 Hardware Manual.
What package type is used for the DF2239FA16V?
The DF2239FA16V uses the TFP-100BV package: a 100-pin Thin Fine-Pitch Plastic Ball Grid Array with 0.5 mm ball pitch and 14 mm × 14 mm body size. This package is explicitly listed in Table 1.2 of the H8S/2239 Hardware Manual Rev. 6.00 as supported for HD64F2239 variants. It provides improved thermal performance and higher I/O density compared to the legacy FP-100BV QFP variant.
How many serial communication interfaces does the DF2239FA16V include?
The DF2239FA16V integrates four independent full-duplex Serial Communication Interfaces (SCI0–SCI3), each supporting asynchronous UART operation with programmable baud rates, framing, and error detection. These SCIs are fully functional in all operating modes except deep standby, and support automatic wakeup from low-power modes via received data. Their pin assignments and multiplexing options are defined in Table 1.2 of the H8S/2239 Hardware Manual.
Is the DF2239FA16V qualified for automotive applications?
No, the DF2239FA16V is classified as a "Standard" quality grade device per Renesas' product grading policy and is intended for industrial, office, and consumer applications-not automotive. It lacks AEC-Q100 qualification, extended temperature range (−40°C to +125°C), and automotive-specific failure-in-time (FIT) metrics. For automotive use, Renesas recommends the RH850 or RL78/F1x families, which are explicitly qualified and supported for vehicle ECU deployment.
