Product details
Overview
DF2239TF16V from Renesas Electronics is a 16-bit flash-based microcontroller in the H8S/2239 Group, featuring an H8S/2000 CPU core, 6-channel 16-bit TPU, 4-channel 8-bit TMR, dual watchdog timers, four SCI interfaces, two optional I²C buses, dual 10-bit D/A converters, and 8-channel 10-bit A/D converter. It operates at up to 25 MHz and supports single 5 V supply operation for industrial control applications.
For engineers reviewing the DF2239TF16V datasheet, DF2239TF16V pinout, DF2239TF16V application, or DF2239TF16V equivalent, key selection considerations include its TFP-100BV 100-pin QFP package, flash programmability, integrated peripheral set (TPU/SCI/I²C/DAC/ADC), and qualification for Standard-grade industrial use per Renesas quality classification.
Technical Context
The DF2239TF16V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, enabling efficient instruction execution and memory-mapped peripheral access. It integrates a Bus Controller (BSC) supporting 16-bit data width, Data Transfer Controller (DTC), dual PC Break Controllers, and Flash Memory Programmable Mode for in-system reprogramming.
Peripheral integration includes six independent 16-bit timer pulse units (TPU) with input capture, output compare, and PWM generation capability; four serial communication interfaces (SCI) supporting asynchronous, clock-synchronous, and smart card modes; and dual 10-bit D/A converters with simultaneous update support - all accessible via dedicated on-chip registers and interrupt vectors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8S/2000 32-bit internal architecture, 16-bit external data bus - enables high-throughput control with compact code footprint and deterministic interrupt latency. |
| Max Clock Frequency | 25 MHz - supports real-time response in motor control and sensor interfacing with sub-40 ns instruction cycle time. |
| Flash Memory | 256 KB on-chip flash - allows full firmware storage, field updates, and secure boot without external memory. |
| A/D Converter | 8-channel 10-bit SAR ADC with 1.6 μs conversion time - suitable for analog sensor acquisition in HVAC and power monitoring. |
| D/A Converter | 2-channel 10-bit voltage-output DAC - provides precise analog actuator control (e.g., valve positioning, bias adjustment). |
| Timer Resources | 6× 16-bit TPU + 4× 8-bit TMR + 2× WDT - enables multi-axis PWM generation, pulse-width measurement, and fail-safe timeout supervision. |
| Serial Interfaces | 4× SCI + 2× optional I²C - supports mixed-protocol communication with displays, EEPROMs, sensors, and host controllers. |
Pinout & Package
DF2239TF16V is housed in a 100-pin TFP-100BV thin fine-pitch quad flat package (7 mm × 7 mm, 0.4 mm pitch), RoHS-compliant and rated for −20°C to +75°C ambient operation. Pin functions are configurable across seven operating modes including Flash Memory Programmable Mode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Single 5 V supply operation; multiple VCC/VSS pairs ensure low-noise digital core and I/O domain decoupling. |
| XTAL, EXTAL | Crystal oscillator inputs | Supports 1–20 MHz crystal or external clock source for system timing; internal oscillator not provided. |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU registers, disables peripherals, and forces boot vector fetch from flash address 0x000000. |
| IRQ0–IRQ7 | Maskable interrupt request inputs | Eight priority-encoded external interrupt pins mapped to dedicated vectors; support edge-triggered detection. |
| PA0–PA3, PB0–PB7, etc. | Multi-function I/O ports | Up to 80 general-purpose I/O pins with programmable direction, pull-up enable, and alternate function mapping (TPU, SCI, ADC, etc.). |
Key Features
| Feature | Design Value |
|---|---|
| F-ZTAT™ Flash Technology | Zero-wait-state 256 KB on-chip flash enables instant code execution and field firmware updates without external memory interface overhead. |
| Integrated DTC | Data Transfer Controller handles memory-to-peripheral DMA without CPU intervention - reduces ISR load in high-bandwidth ADC/SCI streaming. |
| TPU with Dead-Time Insertion | 6-channel 16-bit timer unit supports complementary PWM output with programmable dead-time - essential for 3-phase inverter gate drive safety. |
| Dual Independent WDT | Two watchdog timers (one windowed, one standard) allow hierarchical system supervision - e.g., application-layer timeout + hardware-level fail-safe reset. |
| I/O Port Flexibility | Each port pin supports up to 7 alternate functions (e.g., TPU0A, SCI0TXD, AD00); mode register configuration enables dynamic peripheral remapping. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2239TF16V | Same silicon die and pinout; differs only in Renesas part numbering convention (HD64F prefix denotes flash version). | No functional difference; identical peripheral set, memory map, and electrical specs. | Select HD64F2239TF16V when sourcing from legacy Renesas distribution channels or cross-referencing older design documentation. |
| R5F2239TDFP | Successor in RL78/G13 family; 16-bit core, lower power (1.8–5.5 V), smaller 64-pin LQFP, but reduced peripheral count (no dual DAC, only 1 SCI, 6-channel ADC). | Better suited for battery-powered or space-constrained designs where flash size and analog precision are secondary to power efficiency. | Choose R5F2239TDFP only if migrating to Renesas' newer low-power platform and redesigning PCB layout and firmware abstraction layer. |
Compared with DF2239TF16V, HD64F2239TF16V offers identical functionality under a legacy naming scheme, while R5F2239TDFP trades analog integration and package size for energy efficiency and modern toolchain support - neither is pin-compatible nor drop-in replaceable without hardware and software adaptation.

FAQ
What is the maximum operating frequency of the DF2239TF16V?
The DF2239TF16V supports a maximum system clock frequency of 25 MHz when driven by an external crystal or clock source connected to XTAL/EXTAL. This enables instruction execution at 40 ns per cycle in high-speed mode, sufficient for real-time control loops in motor drives and PLCs. The device does not include an internal RC oscillator; external timing is mandatory.
Does the DF2239TF16V include an internal voltage regulator or require external regulation?
The DF2239TF16V requires a stable 5.0 V ±10% supply applied to VCC pins; it does not integrate a voltage regulator. All VCC/VSS pairs must be independently decoupled with 0.1 μF ceramic capacitors near the package. Operation outside the 4.5–5.5 V range may cause undefined behavior or permanent damage, as confirmed in Renesas' Electrical Characteristics section.
How many analog-to-digital converter channels does the DF2239TF16V support?
The DF2239TF16V integrates an 8-channel, 10-bit successive-approximation (SAR) ADC with a typical conversion time of 1.6 μs. Input channels map to dedicated pins (AD00–AD07) and support software or timer-triggered sampling. The ADC uses an internal reference and is not compatible with external reference voltages per the H8S/2239 Hardware Manual Rev.6.00.
Is the DF2239TF16V qualified for automotive applications?
No, the DF2239TF16V is classified as a Standard-grade Renesas product intended for industrial, office, and consumer equipment per Quality Grade Notice #7. It is not AEC-Q100 qualified, lacks extended temperature range support (−40°C to +125°C), and has no automotive-specific failure-in-time (FIT) data. For automotive use, Renesas recommends RH850 or RL78/F1x families instead.
What debug interface does the DF2239TF16V support for firmware development?
The DF2239TF16V supports on-chip debugging via the H8S/2000 series standard interface using the Renesas E8/E8a emulator or High-performance Embedded Workshop IDE. Debug access uses dedicated pins (MD0, MD1, RES#) and requires no additional debug circuitry - the same pins serve both programming and real-time trace/debug functions during development.
