Product details
Overview
DF2132RTF20V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2132F-ZTAT™ family, featuring a 32-bit H8S/2000 CPU core, 64 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 DF2132RTF20V datasheet, DF2132RTF20V pinout, DF2132RTF20V application, or DF2132RTF20V equivalent, key selection criteria include its 64 KB flash configuration, absence of DTC/I²C/HIF modules (vs. H8S/2138), 3× 8-bit TMR channels, dual DAC outputs, and FP-80A 80-pin QFP package with 64 I/O pins.
Technical Context
The DF2132RTF20V implements the H8S/2000 CPU core with 16 × 16-bit general-purpose registers and supports a 16-Mbyte linear address space. It integrates an 8-bit timer (TMR) module with three independent channels, a 16-bit free-running timer (FRT), and two watchdog timers (WDT) for system supervision.
On-chip analog functions include an 8-input 10-bit successive-approximation ADC with sample-and-hold, two 8-bit D/A converters, and dedicated A/D conversion timing control. Peripheral interfaces comprise three SCI channels (UART/IrDA), but exclude I²C, host interface (HIF), and data transfer controller (DTC) - distinguishing it from higher-tier H8S/2138 variants.
Key Specifications

| Flash Memory | 64 KB F-ZTAT™ flash; supports in-system programming, field updates, and rapid prototyping without mask ROM commitment. |
| ADC | 8-channel 10-bit SAR ADC with sample-and-hold; provides precise analog sensing for battery voltage, temperature, and sensor monitoring. |
| PWM Outputs | Two 14-bit PWMX timers; deliver high-resolution motor control or LED dimming with programmable dead-time and synchronization. |
| Supply Voltage | 4.5 V to 5.5 V operation; ensures compatibility with standard 5 V logic systems and industrial power rails. |
| Max Clock Frequency | 25 MHz; enables sub-40 ns instruction cycle time for responsive interrupt handling and real-time loop execution. |

Pinout & Package
DF2132RTF20V uses the FP-80A 80-pin plastic quad flat pack (QFP) package, measuring 14 mm × 14 mm with 0.65 mm lead pitch. The package supports surface-mount assembly and provides full access to all on-chip peripherals via dedicated and multiplexed pins.
| 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. |
| P10–P17, P20–P27, P30–P37, P40–P47, P50–P57, P60–P67, P80–P87, P90–P97 | General-purpose I/O ports | Eight 8-bit bi-directional ports with individually configurable pull-up; enable flexible peripheral mapping and low-pin-count system design. |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU state and initializes peripherals; requires external RC or supervisor circuit for reliable power-on sequencing. |
| CLK, EXTAL, XTAL | System clock inputs | Supports crystal (1–20 MHz), ceramic resonator, or external clock source; internal oscillator not present - external timing required. |
| AD0–AD7 | Analog input channels | Eight dedicated ADC input pins with shared function on Port 6; allow simultaneous sampling of multiple sensors without external mux. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2132RV | Same 64 KB flash, identical pinout (FP-80A), but mask ROM version - no field reprogramming capability. | Suitable only for high-volume, fixed-function deployments where firmware never changes after production. | Select HD64F2132RV only when cost sensitivity outweighs need for firmware updates or NPI flexibility. |
| H8S/2134F-ZTAT™ | Higher-tier variant with 128 KB flash, DTC, and optional I²C - but lacks HIF and PWMX; different memory map and register layout. | Applicable where larger code footprint or DMA-accelerated data movement is required, but not drop-in compatible. | Choose H8S/2134F-ZTAT™ only after redesigning firmware and PCB to accommodate expanded peripheral set and memory addressing. |
Compared with HD64F2132RV, DF2132RTF20V enables field firmware updates via F-ZTAT™; compared with H8S/2134F-ZTAT™, it trades flash capacity and DTC for lower cost and guaranteed pin compatibility in legacy 64 KB designs.

FAQ
What is the maximum operating frequency of the DF2132RTF20V?
The DF2132RTF20V operates at a maximum clock frequency of 25 MHz. This timing specification is validated under 4.5 V to 5.5 V supply conditions and ambient temperatures from –20°C to +75°C. The DF2132RTF20V achieves sub-40 ns instruction cycle times at this rate, supporting deterministic real-time control loops and fast interrupt response in applications like keyboard scanning and battery monitoring.
Does the DF2132RTF20V include an integrated data transfer controller (DTC)?
No, the DF2132RTF20V does not include a data transfer controller (DTC). Unlike the H8S/2138 Group, the H8S/2132F-ZTAT™ family - including DF2132RTF20V - omits the DTC module. Data movement must be handled by CPU-initiated transfers or peripheral-triggered interrupts. This omission reduces silicon area and cost while maintaining suitability for applications where DMA bandwidth is not critical, such as PC keyboard controllers or basic power supervisors.
What package type and pin count does the DF2132RTF20V use?
The DF2132RTF20V uses the FP-80A package: an 80-pin plastic quad flat pack (QFP) with 0.65 mm lead pitch and 14 mm × 14 mm body size. It provides 64 general-purpose I/O pins plus dedicated power, clock, reset, and debug signals. This package is RoHS-compliant and qualified for surface-mount reflow assembly, matching pinouts with other H8S/2132 variants like HD64F2132RV for direct PCB reuse.
Can the DF2132RTF20V support I²C communication?
No, the DF2132RTF20V does not support I²C communication. The H8S/2132F-ZTAT™ group excludes the I²C bus interface (IIC) module entirely - unlike the H8S/2138 Group, which offers IIC as an option. For two-wire serial communication, designers must implement bit-banged I²C in firmware using GPIO pins or use SCI in synchronous mode with external level-shifting, as no hardware I²C peripheral is present in the DF2132RTF20V.
What is the flash memory endurance and data retention specification for DF2132RTF20V?
The DF2132RTF20V's F-ZTAT™ flash memory guarantees a minimum of 100 write/erase cycles (with typical endurance up to 10,000 cycles) and 10 years of data retention at 25°C. These specifications apply across the full operating temperature range and require adherence to Renesas' recommended programming algorithms and voltage tolerances. The DF2132RTF20V's flash architecture supports sector erase and byte/word programming, enabling robust firmware update mechanisms in field-deployed devices.
