Product details
Overview
DF2134AFA20JG 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 a 16-bit free-running timer. It operates at up to 25 MHz with 5 V supply and targets embedded control in PC peripherals and power management systems.
For engineers reviewing the DF2134AFA20JG datasheet, DF2134AFA20JG pinout, DF2134AFA20JG application, or DF2134AFA20JG equivalent, key selection criteria include its 128 KB flash capacity, absence of DTC/I²C/HIF modules (distinguishing it from H8S/2138), 8-bit TMR count (3 channels), and FP-80A 80-pin QFP package with verified NC pin handling and I/O drive strength specifications.
Technical Context
The DF2134AFA20JG implements the H8S/2000 CPU core with 16 × 16-bit general-purpose registers, supporting a 16-Mbyte linear address space and efficient C-language execution. Its peripheral set includes three independent serial communication interfaces (SCI) with IrDA support, dual 8-bit DACs for analog output generation, and an 8-channel 10-bit ADC with expansion inputs.
It lacks the data transfer controller (DTC), host interface (HIF), and I²C bus interface found in the H8S/2138 Group, confirming its role as a cost-optimized variant within the H8S/2134 family. Power management includes multiple low-power modes-Sleep, Module Stop, Watch, Subactive, Subsleep, Software Standby, and Hardware Standby-with RAM retention and selective peripheral operation.
Key Specifications

Pinout & Package
DF2134AFA20JG is housed in the FP-80A 80-pin plastic quad flat package (QFP), measuring 14 mm × 14 mm with 0.65 mm lead pitch. Pin functions are mode-dependent (Single-Chip Mode 1–3, Flash Programmer Mode), with dedicated pins for reset, clock input (XIN/XOUT), power (VCC/VSS), and multifunction I/O ports (P1–P9).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Primary 5 V supply and reference ground; decoupling required per Renesas layout guidelines to ensure stable core and I/O operation. |
| XIN / XOUT | Crystal oscillator input/output | Supports external crystal (1–20 MHz) or ceramic resonator; configures system clock source for timing-critical peripherals. |
| RESET | Active-low reset input | Asynchronous reset signal; must be held low ≥1024 cycles after power stabilization to guarantee deterministic initialization. |
| P10–P17, P20–P27, etc. | Multi-function I/O ports | Programmable as general-purpose digital I/O, timer inputs/outputs, SCI signals, or ADC inputs; pull-up current configurable per port. |
| P52 / P97 | NMOS push-pull outputs | Drive high-level voltage down to 1.5 V at –1 mA (VCC = 4.5–5.5 V); requires external pull-up for full 5 V logic compatibility. |
| NC Pins | Not connected | Internally unconnected or test-only; must remain unconnected to avoid undefined LSI behavior per Renesas handling precautions. |
Key Features
| Feature | Design Value |
|---|---|
| F-ZTAT™ Flash Memory | 128 KB single-power-supply flash enabling field firmware updates and rapid prototyping without UV erasers or external programmers. |

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 core, 128 KB flash, but mask ROM version (no F-ZTAT™); lacks flash reprogrammability. | Suitable for high-volume, fixed-firmware deployments where field updates are unnecessary. | Select HD64F2134AV only when firmware is finalized and flash endurance/reprogramming is not required. |
| H8S/2138F-ZTAT™ | Includes DTC, I²C, HIF, and 4× TMR channels; adds 16-bit PWM and timer connection capability. | Required for systems needing DMA-accelerated data transfers, I²C sensor networks, or host-side peripheral bridging. | Choose H8S/2138F-ZTAT™ when DTC offload, I²C connectivity, or enhanced timer interconnectivity are mandatory design requirements. |
Compared with HD64F2134AV, DF2134AFA20JG offers field-upgradable firmware via F-ZTAT™ flash; compared with H8S/2138F-ZTAT™, it reduces BOM cost and layout complexity by omitting DTC, I²C, and HIF-making it optimal for cost-sensitive, self-contained control applications.

FAQ
What is the maximum operating frequency of the DF2134AFA20JG?
The DF2134AFA20JG supports a maximum system clock frequency of 25 MHz, achieved using an external crystal or ceramic resonator connected to the XIN/XOUT pins. This frequency determines instruction execution speed and peripheral timing resolution, and must be maintained within the 4.5 V to 5.5 V supply range to ensure stable operation per Renesas Electrical Characteristics specifications.
Does the DF2134AFA20JG include a data transfer controller (DTC)?
No, the DF2134AFA20JG does not include a data transfer controller (DTC). As confirmed in the H8S/2134 Group functional comparison table, DTC is exclusive to the H8S/2138 Group. DF2134AFA20JG relies on CPU-managed data movement, making it suitable for applications where peripheral bandwidth and interrupt load do not require DMA acceleration.
What are the flash memory endurance and data retention specifications for DF2134AFA20JG?
The DF2134AFA20JG features 128 KB of F-ZTAT™ flash memory rated for a minimum of 100 erase/write cycles (guaranteed) and up to 10,000 cycles (reference value at 25°C), with 10-year data retention under specification conditions. These values are documented in Table 25.27 and Table 25.49 of the H8S/2134 Group Hardware Manual Rev. 4.00.
Which communication interfaces are supported by the DF2134AFA20JG?
The DF2134AFA20JG integrates three serial communication interfaces (SCI) supporting UART and IrDA protocols, plus dual 8-bit DACs and an 8-channel 10-bit ADC-but no I²C or host interface (HIF). This makes it ideal for point-to-point serial control and analog I/O, while excluding multi-master bus topologies or PC-host bridging applications.
How is the DF2134AFA20JG packaged, and what are critical layout considerations?
DF2134AFA20JG uses the FP-80A 80-pin plastic QFP package (14 mm × 14 mm, 0.65 mm pitch). Critical layout considerations include strict adherence to Renesas' NC pin handling rule (leave unconnected), placement of 0.1 µF ceramic decoupling capacitors near each VCC pin, and routing of XIN/XOUT traces as matched-length, shielded differential pairs to minimize oscillator jitter and startup failure.
