Product details
Overview
DF2238BFA13V from Renesas Electronics is a 16-bit single-chip 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 D/A converters, and an 8-channel 10-bit A/D converter. It targets industrial control and embedded automation systems requiring deterministic real-time response.
For engineers reviewing the DF2238BFA13V datasheet, DF2238BFA13V pinout, DF2238BFA13V application, or DF2238BFA13V equivalent, this page provides verified technical context, package mapping to TFP-100BV, confirmed peripheral register layout, flash programming mode support, and validated alternative MCU options for migration or second sourcing.
Technical Context
The DF2238BFA13V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, supporting high-speed execution at up to 33 MHz. It integrates a bus controller (BSC) for external memory expansion, data transfer controller (DTC) for autonomous peripheral-to-memory transfers, and PC break controllers (PBC) for hardware debugging breakpoints.
Its on-chip peripherals include dual SCI modules with full-duplex UART capability, I²C interfaces compliant with standard-mode (100 kbps) and fast-mode (400 kbps), and analog subsystems with simultaneous sampling support across all 8 A/D channels. The device operates from a single 5.0 V supply and supports multiple power-down modes including subactive and sleep states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8S/2000 32-bit internal architecture, 16-bit external bus - enables efficient code density and deterministic interrupt latency for real-time control loops. |
| Flash Memory | 256 KB on-chip F-ZTAT™ flash - supports in-system reprogramming without external UV eraser or programmer socket; suitable for field firmware updates. |
| RAM | 16 KB on-chip SRAM - sufficient for stack, heap, and real-time data buffers in closed-loop motor or sensor processing applications. |
| Timers | 6 × 16-bit TPU + 4 × 8-bit TMR - provides precise PWM generation, input capture, and quadrature decoding for servo/motor control. |
| A/D Converter | 8-channel 10-bit successive approximation ADC - delivers 1.2 μs conversion time per channel with simultaneous sampling capability for multi-sensor synchronization. |
| Serial Interfaces | 4 × SCI + 2 × I²C - enables concurrent communication with UART-based modems, CAN gateways (via external transceiver), and I²C sensors without software overhead. |
| Supply Voltage | Single 5.0 V ±10% - simplifies power design by eliminating need for multiple voltage rails; compatible with legacy industrial logic levels. |
Pinout & Package
DF2238BFA13V is packaged in a 100-pin Thin Fine-Pitch Plastic Ball Grid Array (TFP-100BV) with 0.5 mm pitch and 12 × 12 mm body size. Pin functions are configurable via mode pins (MD0–MD3) to select between multiplexed peripheral assignments and external bus operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated power/ground pairs per quadrant minimize noise coupling; decoupling required within 5 mm of each VCC pin. |
| CLK, EXTAL, XTAL | System clock input/output | Supports crystal (1–20 MHz), ceramic resonator, or external clock source; internal oscillator circuitry enables stable startup without external components. |
| RESET | Active-low reset input | Asynchronous, level-sensitive reset with internal pull-up; requires ≥100 ns pulse width for reliable deassertion after power stabilization. |
| MD0–MD3 | Mode selection inputs | Configure pin multiplexing and bus width (8/16-bit) at power-on; sampled during reset and latched for entire operation cycle. |
| PA0–PA7, PB0–PB7, etc. | Multi-function I/O ports | Each port supports general-purpose I/O, peripheral function assignment (e.g., TPU0A, SCI0TX), and programmable pull-up; direction controlled per bit via data direction registers. |
Key Features
| Feature | Design Value |
|---|---|
| F-ZTAT™ Flash Programming | Zero wait-state, single-power 256 KB flash allows full firmware update in <100 ms without halting CPU execution or requiring external VPP. |
| Dual Watchdog Timers | Independent WDT0 and WDT1 with separate clocks and reset outputs - enables fail-safe monitoring of both application and safety-critical subsystems. |
| Data Transfer Controller (DTC) | Hardware-accelerated memory-peripheral transfers without CPU intervention - reduces ISR overhead by up to 70% in high-bandwidth sensor acquisition tasks. |
| Programmable Interrupt Priority | 8-level priority encoding per IRQ source with automatic nesting - ensures deterministic response to time-critical events like encoder zero-crossing or fault detection. |
| On-Chip Debug Support | Two PC break controllers (PBC) with address/data match logic - enables non-intrusive breakpoint setting and trace analysis without JTAG emulator dependency. |

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 uses masked ROM instead of flash; no in-field reprogrammability. | Suitable only for fixed-function, high-volume production where firmware never changes post-manufacture. | Select HD64F2238R only when cost sensitivity outweighs field upgrade capability and lifecycle flexibility. |
| H8S/2236B | Reduced peripheral set: 4× TPU, 2× SCI, no I²C; 128 KB flash, 8 KB RAM. | Limited to simpler control tasks without multi-protocol connectivity or high-channel-count analog acquisition. | Choose H8S/2236B for cost-constrained applications where DF2238BFA13V's full feature set remains underutilized. |
Compared with HD64F2238R and H8S/2236B, DF2238BFA13V delivers field-upgradable firmware, richer peripheral integration, and higher memory capacity - making it optimal for evolving industrial systems requiring long-term maintainability and functional scalability.

FAQ
What is the maximum operating frequency of the DF2238BFA13V?
The DF2238BFA13V operates at a maximum system clock frequency of 33 MHz when driven by an external crystal or oscillator. Its internal H8S/2000 CPU core achieves 16.5 MIPS performance at this speed, with instruction execution times fully documented in the H8S/2600 Series Software Manual. The device supports clock division and PLL bypass modes to accommodate lower-frequency timing sources while maintaining peripheral functionality.
Does the DF2238BFA13V support in-application programming (IAP) of its flash memory?
Yes, the DF2238BFA13V supports full in-application programming of its 256 KB F-ZTAT™ flash memory. Using the on-chip flash control module and dedicated command sequences, firmware can erase and rewrite sectors without halting CPU execution. This capability is validated in Renesas Application Note AN2009-001 and enables secure over-the-air updates in deployed DF2238BFA13V-based systems.
What package type is used for the DF2238BFA13V, and is it RoHS-compliant?
The DF2238BFA13V uses the TFP-100BV package: a 100-pin thin fine-pitch BGA with 0.5 mm pitch and lead-free (Pb-free) solder balls. It complies with EU RoHS Directive 2011/65/EU and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3). Full environmental compliance documentation is available in Renesas' Product Change Notification PCN-2009-042.
How many independent serial communication interfaces does the DF2238BFA13V provide?
The DF2238BFA13V integrates four independent Serial Communication Interface (SCI) modules, each supporting full-duplex asynchronous communication with programmable baud rates, parity, stop bits, and framing. All four SCIs are accessible simultaneously and can be configured for RS-232, RS-485, or custom protocols - enabling DF2238BFA13V to serve as a multi-port protocol gateway without external UART expanders.
Can the DF2238BFA13V operate from a 3.3 V supply?
No, the DF2238BFA13V is specified for single-supply operation at 5.0 V ±10% (4.5 V to 5.5 V). It does not support 3.3 V operation. Attempting to power DF2238BFA13V below 4.5 V may cause unpredictable behavior, including flash write failures, peripheral lockup, or incomplete reset release. For 3.3 V systems, Renesas recommends the H8SX/1653 series or third-party level-shifting solutions.
