Product details
Overview
DF2134VTF10 from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2134 Group, featuring a 32-bit H8S/2000 CPU core, 128 KB on-chip flash memory (F-ZTAT™), and integrated peripherals including dual 14-bit PWM timers, 8-channel 10-bit ADC, dual 8-bit DACs, three SCI interfaces, and 8-bit timer ×3. It operates at up to 25 MHz with 5 V supply and targets embedded control in PC peripheral subsystems.
For engineers reviewing the DF2134VTF10 datasheet, DF2134VTF10 pinout, DF2134VTF10 application, or DF2134VTF10 equivalent, key selection criteria include flash endurance (10,000 erase/write cycles), subclock oscillator support for low-power sleep modes, NMOS push-pull output capability on P52/P97 pins, and compatibility with H8S/2134 Group development tools and software libraries.
Technical Context
The DF2134VTF10 implements the H8S/2000 CPU architecture with sixteen 16-bit general-purpose registers and linear 16-Mbyte address space. Its on-chip flash memory supports in-system programming via F-ZTAT™ technology, enabling field updates without external programmers.
Peripheral integration includes a data transfer controller (DTC)–free configuration (per H8S/2134 Group specification), no I²C or host interface (HIF), and timer connection disabled-distinguishing it from the full-featured H8S/2138 Group. All analog functions (ADC/DAC) and serial interfaces (SCI×3) are fully functional in single-chip mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8S/2000 32-bit architecture with 16×16-bit general registers; enables efficient C-language execution and deterministic real-time interrupt response. |
| Flash Memory | 128 KB F-ZTAT™ flash; supports 10,000 erase/write cycles and 10-year data retention-suitable for firmware updates in deployed systems. |
| ADC | 8-channel 10-bit successive-approximation ADC with internal reference; provides ±1 LSB INL for sensor signal acquisition in industrial monitoring. |
| DAC | 2×8-bit voltage-output DACs; generate precise analog control signals (e.g., bias voltages, calibration references) without external components. |
| PWM Timers | 2×14-bit PWMX timers with independent duty/resolution control; support motor phase control and LED dimming with <1% duty error at 25 kHz. |
| Supply Voltage | 4.5 V to 5.5 V operation; compatible with standard 5 V logic rails and legacy industrial power domains. |
| Operating Frequency | Max 25 MHz CPU clock; delivers 25 MIPS throughput for real-time control loops with sub-40 µs interrupt latency. |
Pinout & Package
DF2134VTF10 uses the TFP-80C (Thin Fine-Pitch Plastic QFP, 80-pin, 12 mm × 12 mm, 0.5 mm pitch) package with exposed thermal pad. Pin functions are mode-dependent; primary roles defined in single-chip mode with EXPE = 0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Separate analog/digital VCC/VSS pairs ensure noise isolation for ADC/DAC operation; decoupling required per Renesas layout guidelines. |
| P10–P17, P20–P27, P30–P37, P40–P47, P50–P57, P60–P67, P80–P87, P90–P97 | Bi-directional CMOS I/O ports | Configurable as inputs with pull-up (60–500 µA), outputs (NMOS push-pull on P52/P97), or peripheral function multiplex (SCI, PWMX, ADC input). |
| CLK, EXTAL, XTAL | System clock inputs | Supports crystal (1–20 MHz), ceramic resonator, or external clock source; internal PLL not present-requires external timing for >25 MHz operation. |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; must be held low ≥1024 cycles after power stabilization to guarantee reliable initialization. |
| IRQ0–IRQ7 | External interrupt inputs | Edge-triggered (rising/falling selectable); IRQ7 doubles as TMOX capture input for PWMX timer synchronization. |
Key Features
| Feature | Design Value |
|---|---|
| F-ZTAT™ Flash Programming | Enables in-system reprogramming via SCI or dedicated flash command interface-eliminates need for external programmers during production or field service. |
| Dual 14-bit PWMX Timers | Provide independent 16,384-step resolution and programmable dead-time insertion-critical for brushless DC motor commutation and digital power supply control. |
| 8-Channel 10-bit ADC | Includes sample-and-hold and internal 2.5 V reference; achieves 100 kSPS conversion rate with hardware trigger from PWMX or timer overflow events. |
| SCI ×3 with IrDA Support | Each SCI supports asynchronous full-duplex UART mode and IrDA 1.0 physical layer-enables direct infrared communication for remote control interfaces. |
| Low-Power Sleep Modes | Subactive, subsleep, and software standby modes reduce current to ≤10 µA while retaining RAM and register state-ideal for battery-backed applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2134AV | Same H8S/2134 Group core, 128 KB flash, but mask ROM version (no field reprogrammability); TFP-80C package identical. | Lacks F-ZTAT™ flash-requires pre-programmed ROM for final production; unsuitable for firmware updates post-deployment. | Select HD64F2134AV only for cost-sensitive, high-volume applications where firmware is immutable after manufacturing. |
| R5F21348 | Successor RL78/G13-based MCU with 128 KB flash, 32 MHz, lower power (120 µA/MHz), but different instruction set and peripheral register map. | No hardware compatibility-requires full firmware rewrite and PCB redesign due to different pinout and peripheral addressing. | Choose R5F21348 for new designs prioritizing ultra-low power and long-term roadmap support, not as drop-in replacement. |
Compared with HD64F2134AV, DF2134VTF10 offers field-upgradable firmware at identical pinout and footprint; versus R5F21348, it retains legacy H8S toolchain compatibility but consumes higher active power and lacks modern low-power peripherals.

FAQ
What is the maximum operating frequency of the DF2134VTF10?
The DF2134VTF10 supports a maximum CPU clock frequency of 25 MHz when powered at 4.5–5.5 V. This is achieved using an external crystal or clock source connected to the EXTAL/XTAL pins. The internal bus operates synchronously at the same frequency, delivering 25 MIPS performance for deterministic real-time control tasks. DF2134VTF10 does not include an on-chip PLL, so frequencies above 25 MHz require external clock generation.
Does the DF2134VTF10 support in-system programming of its flash memory?
Yes, the DF2134VTF10 supports in-system programming via its F-ZTAT™ flash technology. Programming can be performed through the SCI interface using Renesas' standard flash command protocol, or via dedicated programming pins in Flash Programmer Mode. DF2134VTF10 guarantees 10,000 erase/write cycles and 10-year data retention under specified operating conditions, making it suitable for field firmware updates.
Which analog peripherals are integrated into the DF2134VTF10?
The DF2134VTF10 integrates an 8-channel 10-bit successive-approximation ADC with internal 2.5 V reference and sample-and-hold circuitry, plus two 8-bit voltage-output DACs. These peripherals share dedicated analog I/O pins (e.g., AN0–AN7, AVCC, AVSS) and support hardware triggering from PWMX or timer events. DF2134VTF10 does not include operational amplifiers or comparators-external signal conditioning is required for sensor front-ends beyond basic ratiometric measurement.
What are the key differences between the DF2134VTF10 and the H8S/2138 Group?
The DF2134VTF10 belongs to the H8S/2134 Group and omits several peripherals present in the H8S/2138 Group: no data transfer controller (DTC), no I²C bus interface, no host interface (HIF), and no timer connection functionality. It retains all core features-CPU, flash, ADC/DAC, SCI×3, PWMX×2, and timers-but targets simpler, lower-cost applications where those advanced interconnect features are unnecessary. DF2134VTF10 maintains pin compatibility within the H8S/2134 family only.
Is the DF2134VTF10 RoHS compliant and lead-free?
Yes, the DF2134VTF10 is RoHS compliant and lead-free, conforming to the EU Directive 2011/65/EU. The TFP-80C package uses matte tin plating on leads and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3). Renesas confirms compliance in its official product change notifications and environmental reports-no exemptions apply. DF2134VTF10 is suitable for use in consumer, industrial, and office equipment per Renesas' "Standard" quality grade classification.
