Product details
Overview
DF2238BTE13V from Renesas Electronics is a 16-bit flash microcontroller in the H8S/2238 Group, featuring an H8S/2000 CPU core, 256 KB on-chip flash memory, 16 KB RAM, and integrated peripherals including six 16-bit timer pulse units (TPU), four 8-bit timers (TMR), dual watchdog timers (WDT), four serial communication interfaces (SCI), two I²C buses, two 10-bit D/A converters, and eight-channel 10-bit A/D converter - deployed in industrial control panels requiring deterministic real-time response.
For engineers reviewing the DF2238BTE13V datasheet, DF2238BTE13V pinout, DF2238BTE13V application, or DF2238BTE13V equivalent, key selection criteria include flash endurance (10,000 write/erase cycles), operating voltage range (3.0–5.5 V), −40°C to +85°C industrial temperature grade, and TFP-100BV 100-pin thin fine-pitch QFP package compatibility with legacy H8S/2238B designs.
Technical Context
The DF2238BTE13V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, supporting high-speed instruction execution at up to 33 MHz CPU clock (with 2× PLL multiplier). It integrates a bus controller (BSC) for external memory expansion and a data transfer controller (DTC) for autonomous peripheral-to-memory transfers without CPU intervention.
Its peripheral set includes dual SCI modules supporting asynchronous full-duplex communication with programmable baud rates, two I²C interfaces compliant with standard/fast-mode (100/400 kbps), and analog functions with simultaneous sampling capability across all eight A/D input channels - enabling synchronized sensor acquisition in motor control feedback loops.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2238R | Same H8S/2238 core, but mask ROM instead of flash; no in-system reprogrammability. | Suitable only for fixed-function, high-volume production where firmware never changes. | Select HD64F2238R only when firmware is finalized and cost-per-unit optimization outweighs field update capability. |
| R5F52238ADFP | RX220-series 32-bit MCU with higher performance (50 MHz), larger RAM (32 KB), and enhanced peripheral set (USB, CAN). | Requires PCB redesign due to different pinout, voltage levels, and debug interface (SWD vs. H8S JTAG). | Choose R5F52238ADFP when migrating to next-generation platforms needing USB connectivity, CAN bus, or higher computational throughput. |
Compared with HD64F2238R and R5F52238ADFP, DF2238BTE13V uniquely balances legacy H8S software compatibility, field-upgradable flash, and industrial-grade packaging - making it optimal for sustaining existing H8S-based designs while retaining upgrade path flexibility.

FAQ
What is the maximum operating frequency of the DF2238BTE13V?
The DF2238BTE13V supports a maximum CPU clock frequency of 33 MHz when using the on-chip PLL with a 16.5 MHz crystal input. This frequency is achievable across the full −40°C to +85°C industrial temperature range and 3.0–5.5 V supply voltage, enabling deterministic real-time execution for time-critical control tasks in the DF2238BTE13V.
Does the DF2238BTE13V support in-system programming (ISP)?
Yes, the DF2238BTE13V supports in-system programming via its on-chip F-ZTAT™ flash memory. Programming can be performed through the on-chip debug interface (OCDS) using standard JTAG tools, allowing firmware updates without removing the DF2238BTE13V from the target board.
What package type is used for the DF2238BTE13V?
The DF2238BTE13V is supplied in the TFP-100BV package: a 100-pin thin fine-pitch quad flat package with 0.5 mm lead pitch and 14 mm × 14 mm body size. This package includes an exposed thermal pad and is RoHS-compliant, matching pinout compatibility with other H8S/2238B variants.
How many analog-to-digital converter (ADC) channels does the DF2238BTE13V have?
The DF2238BTE13V integrates an 8-channel, 10-bit successive-approximation ADC with sample-and-hold capability. All channels support simultaneous triggering via TPU or software start, and conversion times as low as 1.2 μs per channel - critical for synchronized sensor acquisition in the DF2238BTE13V.
Is the DF2238BTE13V qualified for automotive applications?
No, the DF2238BTE13V is rated for industrial temperature range (−40°C to +85°C) and classified as a "Standard" quality grade device per Renesas documentation. It is not AEC-Q100 qualified and lacks the extended temperature range, enhanced ESD immunity, and automotive-specific qualification required for automotive applications - use only in industrial, commercial, or test equipment contexts per the DF2238BTE13V datasheet guidance.
