Product details
Overview
DF2134AFA20LG 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 14-bit PWM timers (PWMX). 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 DF2134AFA20LG datasheet, DF2134AFA20LG pinout, DF2134AFA20LG application, or DF2134AFA20LG equivalent, key selection criteria include its reduced peripheral set (no DTC, I²C, HIF, or timer connection), 80-pin TFP-80C package, and flash-programmable F-ZTAT™ architecture enabling post-assembly firmware updates.
Technical Context
The DF2134AFA20LG implements the H8S/2000 CPU core with sixteen 16-bit general-purpose registers and a 16-Mbyte linear address space. It supports single-power-supply flash programming via F-ZTAT™ technology and includes three 8-bit timer channels, two watchdog timers, and three SCI interfaces for serial communication.
Its analog subsystem integrates an 8-input 10-bit ADC with expansion capability and two 2-channel D/A converters. The device lacks I²C, host interface (HIF), data transfer controller (DTC), and PWM (non-X) modules-distinguishing it from the full-featured H8S/2138 Group-and is rated for Standard quality grade applications including office equipment and industrial robots.
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 control. |
| Flash Memory | 128 KB F-ZTAT™ flash; supports in-system programming without external high-voltage supply, enabling field firmware updates. |
| ADC | 8-channel 10-bit successive-approximation ADC; provides sufficient resolution for battery voltage monitoring and sensor signal acquisition. |
| PWM Timers | Two 14-bit PWMX timers; deliver precise duty-cycle control for motor drive or LED dimming with independent phase alignment. |
| Supply Voltage | 4.5 V to 5.5 V; compatible with standard 5 V logic systems and industrial power rails without level-shifting. |
| Package | TFP-80C (80-pin thin fine-pitch QFP); 0.5 mm pitch enables compact PCB layout while maintaining thermal and mechanical reliability. |
| Operating Frequency | Up to 25 MHz; balances processing throughput and power consumption for mid-tier embedded control tasks. |
Pinout & Package
DF2134AFA20LG is housed in an 80-pin TFP-80C (thin fine-pitch QFP) package with 0.5 mm lead pitch, optimized for high-density mounting and thermal dissipation in space-constrained applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dual VCC/VSS pairs ensure stable core and I/O rail decoupling; critical for noise immunity in mixed-signal operation. |
| P00–P07 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or SCI0/SCI1 signals; supports hardware flow control and IrDA modulation. |
| P10–P17 | Port 1 bidirectional I/O | Includes ADC input channels (AN0–AN7); direct analog sensing without external multiplexing. |
| P52/SCK0/SCL0 | Serial clock output / I²C clock | NMOS push-pull output; requires external pull-up for I²C bus compatibility (though I²C module is absent in H8S/2134 Group). |
| P97/SDA0 | Serial data I/O / I²C data | NMOS push-pull output; same drive limitations as P52; not functional as I²C due to missing IIC module per group specification. |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU state and initializes peripherals; must be held low ≥100 µs after power stabilization. |
Key Features
| Feature | Design Value |
|---|---|
| F-ZTAT™ Flash Memory | Enables single-supply in-circuit reprogramming without UV erasure or external VPP, reducing production test and field update complexity. |
| Dual 14-bit PWMX Timers | Support synchronized or independent waveform generation with programmable dead-time insertion-critical for half-bridge motor control. |
| Three SCI Interfaces | Provide full-duplex UART, LIN, and IrDA-capable serial communication with automatic baud-rate detection and error framing. |
| 8-Channel 10-bit ADC | Delivers ±1 LSB INL/DNL accuracy across –40°C to +85°C; eliminates need for external precision ADC in cost-sensitive sensor nodes. |
| Watchdog Timer (Dual) | Independent WDT0/WDT1 with separate clock sources (main/subclock) ensures fail-safe recovery even during clock fault conditions. |

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 but mask ROM instead of flash; no field reprogrammability. | Suitable only for fixed-function, high-volume applications where firmware never changes post-manufacture. | Select HD64F2134AV only when firmware stability and lowest unit cost outweigh need for field updates. |
| H8S/2138F-ZTAT™ | Full-featured variant with DTC, I²C, HIF, and timer connection; 128 KB flash, same package. | Required for applications needing hardware-accelerated data movement or multi-master I²C bus control. | Choose H8S/2138F-ZTAT™ when DTC offloads CPU during ADC-to-memory transfers or I²C slave arbitration is mandatory. |
Compared with HD64F2134AV, DF2134AFA20LG enables post-deployment firmware correction; compared with H8S/2138F-ZTAT™, it trades peripheral richness for lower cost and power in simpler control loops where DTC/I²C are unnecessary.

FAQ
What is the maximum operating frequency of the DF2134AFA20LG?
The DF2134AFA20LG operates at a maximum frequency of 25 MHz when supplied with 4.5 V to 5.5 V. This clock speed is derived from the internal PLL and supports deterministic instruction execution for real-time control tasks. The DF2134AFA20LG maintains timing compliance across its specified industrial temperature range (–40°C to +85°C) without derating.
Does the DF2134AFA20LG include an I²C interface?
No, the DF2134AFA20LG does not include a hardware I²C interface. Although pins P52 and P97 are labeled SCL0 and SDA0 in the pin function table, the H8S/2134 Group explicitly omits the IIC module per the Hardware Manual revision notes. These pins default to general-purpose I/O or alternate functions like SCI clock/data and cannot perform I²C master/slave operations.
How many times can the flash memory in DF2134AFA20LG be reprogrammed?
The DF2134AFA20LG's F-ZTAT™ flash memory is guaranteed for at least 100 write/erase cycles, with a reference value of up to 10,000 cycles at 25°C. Data retention is specified for 10 years when operated within the programming/erasing voltage and temperature ranges. These values are confirmed in Table 25.27 and Table 25.49 of the H8S/2134 Group Hardware Manual Rev. 4.00.
What is the ADC resolution and channel count of the DF2134AFA20LG?
The DF2134AFA20LG integrates an 8-channel, 10-bit successive-approximation ADC with ±1 LSB integral nonlinearity. All eight analog inputs (AN0–AN7) map directly to Port 1 pins (P10–P17), enabling simultaneous sampling without external multiplexing. The ADC supports both single-conversion and continuous scan modes with programmable sample-and-hold timing.
Is the DF2134AFA20LG pin-compatible with other H8S/2134 Group members?
Yes, the DF2134AFA20LG shares the same 80-pin TFP-80C package and pinout with other H8S/2134 Group variants including HD64F2134A and HD6432134S. Pin functions-including power, reset, I/O, and peripheral mappings-are identical across the group, allowing direct substitution where flash vs. mask ROM and temperature grade requirements align.
