Product details
Overview
DF2134AVTF10V from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2134 Group, featuring a 32-bit H8S/2000 CPU core, 128 KB on-chip flash memory (F-ZTAT™), 8-channel 10-bit ADC, and dual 2-channel 14-bit PWM timers (PWMX). It operates at up to 25 MHz with 5 V supply and supports intelligent battery management and PC peripheral control.
For engineers reviewing the DF2134AVTF10V datasheet, DF2134AVTF10V pinout, DF2134AVTF10V application, or DF2134AVTF10V equivalent, key selection criteria include its 8-bit timer count (×3), absence of DTC/I²C/HIF modules, 80-pin TFP-80C package, and flash endurance of 10,000 erase/write cycles - critical for firmware-updatable embedded systems.
Technical Context
The DF2134AVTF10V implements the H8S/2000 CPU core with sixteen 16-bit general-purpose registers and a 16-Mbyte linear address space. It integrates on-chip peripherals including three 8-bit timers (TMR), two 14-bit PWM timers (PWMX), one 16-bit free-running timer (FRT), dual 2-channel DACs, and an 8-input 10-bit ADC with expansion capability.
It lacks data transfer controller (DTC), I²C bus interface (IIC), host interface (HIF), and timer connection functionality - distinguishing it from the full-featured H8S/2138 Group. Boot mode supports RAM-based programming control in reserved areas (e.g., H'FFE080–H'FFEFFF for 128 KB versions).
Key Specifications

|---|---|
| CPU Core | H8S/2000 32-bit architecture with 16-bit register file; enables efficient C-language execution and deterministic real-time control. |
| Flash Memory | 128 KB F-ZTAT™ flash; supports in-system programming and field firmware updates without external EPROM programmers. |
| ADC | 8-channel 10-bit successive-approximation ADC with expansion inputs; suitable for analog sensor monitoring in power management systems. |
| PWM Timers | Two independent 14-bit PWMX channels; provides high-resolution motor control or LED dimming with programmable duty cycle and period. |
| Operating Voltage | 4.5 V to 5.5 V; compatible with standard 5 V industrial and PC peripheral power rails, with guaranteed DC characteristics across range. |
| Max Clock Frequency | 25 MHz; delivers sufficient throughput for keyboard controllers, battery fuel gauges, and monitor timing logic without external clock synthesis. |
| Package | TFP-80C (80-pin thin fine-pitch QFP); 0.5 mm pitch, 12 mm × 12 mm footprint; optimized for compact PCB layouts in space-constrained applications. |
Pinout & Package
DF2134AVTF10V is housed in a TFP-80C (80-pin thin fine-pitch QFP) package with 0.5 mm lead pitch and 12 mm × 12 mm body size. Pin functions are mode-dependent (Single-Chip Mode 1/2/3, Flash Programmer Mode), with shared roles across timer, serial, analog, and I/O resources.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dual VCC/VSS pairs ensure stable core and I/O rail decoupling; required for noise immunity in mixed-signal operation. |
| P00–P07 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or SCI0/SCI1 signal lines; supports UART communication for host diagnostics or firmware updates. |
| P52/SCK0/SCL0 | Shared function pin | NMOS push-pull output for SPI clock (SCK0) or I²C clock (SCL0); requires external pull-up for open-drain I²C use. |
| P97/SDA0 | Shared function pin | NMOS push-pull output for I²C data (SDA0); low VOH (1.5 V @ –1 mA) mandates external pull-up for 3.3 V/5 V bus compatibility. |
| AD0–AD7 | Analog input channels | Direct connection to 10-bit ADC inputs; supports simultaneous sampling of battery voltage, temperature, current sense, and auxiliary sensors. |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU state and initializes peripherals; must be held low ≥100 ns after VCC stabilization. |
Key Features
| Feature | Design Value |
|---|---|
| F-ZTAT™ Flash Memory | 128 KB single-power-supply flash enabling zero-cost field firmware updates and rapid prototyping without mask ROM NRE charges. |
| Dual 14-bit PWMX Timers | Independent channel control with programmable resolution; supports precise motor phase timing or multi-zone LED brightness regulation. |
| 8-Channel 10-bit ADC | Hardware-triggered conversion with expansion inputs; eliminates need for external multiplexers in multi-sensor battery monitoring systems. |
| Three 8-bit Timer Channels | Configurable as interval timers, event counters, or input capture units; provides flexible time-base generation for system watchdogs or debounce logic. |
| SCI ×3 Interfaces | Full-duplex UART support on P0/P1/P2 ports; enables concurrent communication with host MCU, display controller, and debug interface. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2134AV | Same core, same peripheral set, but in FP-80A (standard QFP) package; no TFP-80C thermal enhancement. | Less suitable for thermally constrained environments requiring lower junction-to-ambient resistance. | Select HD64F2134AV only when board layout allows standard QFP footprint and thermal budget permits higher θJA. |
| H8S/2134F-ZTAT™ | Identical functional specification and pinout; "F-ZTAT™" denotes flash version branding used in Renesas documentation pre-2010 rebranding. | No functional difference; legacy naming reflects same silicon revision and qualification status. | DF2134AVTF10V and H8S/2134F-ZTAT™ are identical devices - the former is the post-merger part number reflecting Renesas Electronics' naming convention. |
Compared with HD64F2134AV, DF2134AVTF10V offers improved thermal performance via TFP-80C packaging, while H8S/2134F-ZTAT™ is a nomenclature-equivalent designation confirming identical silicon, flash endurance (10,000 cycles), and 128 KB program memory - making DF2134AVTF10V the authoritative current-part-number reference.

FAQ
What is the maximum operating frequency of the DF2134AVTF10V?
The DF2134AVTF10V operates at a maximum clock frequency of 25 MHz under specified conditions (VCC = 4.5 V to 5.5 V, TA = –20°C to +75°C). This frequency is supported by the internal oscillator circuit and external crystal or ceramic resonator configurations documented in the H8S/2134 hardware manual. The DF2134AVTF10V maintains full peripheral functionality-including ADC conversion time and PWM resolution-at this speed.
Does the DF2134AVTF10V include an I²C interface?
No, the DF2134AVTF10V does not include an on-chip I²C bus interface (IIC). Unlike the H8S/2138 Group, the H8S/2134 Group-of which DF2134AVTF10V is a member-omits IIC, DTC, HIF, and timer connection modules. Pins P52 and P97 support SCL0/SDA0 functions only in H8S/2138 devices; on DF2134AVTF10V, these pins serve as NMOS push-pull outputs for SPI or general I/O.
What is the flash memory endurance and data retention for DF2134AVTF10V?
The DF2134AVTF10V features 128 KB of F-ZTAT™ flash memory rated for ≥10,000 erase/write cycles and 10 years of data retention at 25°C. These specifications are guaranteed across the full operating temperature range and apply to all sectors of the flash array. Retention degrades predictably at elevated temperatures per JEDEC JESD22-A117 standards, with no derating required for typical industrial ambient conditions.
Which package type is used for DF2134AVTF10V?
The DF2134AVTF10V uses the TFP-80C package: an 80-pin thin fine-pitch quad flat package with 0.5 mm lead pitch and 12 mm × 12 mm body size. This package provides lower thermal resistance than the legacy FP-80A variant and is optimized for high-density PCB layouts in space-constrained applications such as laptop daughterboards and monitor control modules.
How many ADC channels does the DF2134AVTF10V support?
The DF2134AVTF10V integrates an 8-channel 10-bit successive-approximation ADC with dedicated analog input pins AD0–AD7. It also supports expansion inputs via shared port pins, enabling up to 8 additional analog sources through software-configured multiplexing - totaling 16 usable analog measurement points in systems requiring comprehensive sensor coverage.
