Product details
Overview
DF2132RFA20V 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™), and integrated peripherals including dual 14-bit PWM timers (PWMX), 16-bit free-running timer (FRT), triple SCI interfaces, dual D/A converters, and 8-channel 10-bit A/D converter. It operates at up to 25 MHz with 5 V supply and targets embedded control in PC peripheral subsystems.
For engineers reviewing the DF2132RFA20V datasheet, DF2132RFA20V pinout, DF2132RFA20V application, or DF2132RFA20V equivalent, key selection criteria include its 64 KB F-ZTAT™ flash architecture, absence of DTC/I²C/HIF modules (vs. H8S/2138), 80-pin TQFP package, and support for boot-mode programming via dedicated RAM area H'(FF)E880–H'(FF)EFFF.
Technical Context
The DF2132RFA20V implements the H8S/2000 CPU core with 16 × 16-bit general-purpose registers, linear 16-Mbyte address space, and C-optimized instruction set. It supports single-power-supply flash programming and executes basic instructions in one state.
Its peripheral set includes three SCI modules (full-duplex UART with IrDA support), two 14-bit PWMX timers with independent duty-cycle control, an 8-channel 10-bit ADC with sample-and-hold, and dual 8-bit DACs. The device lacks data transfer controller (DTC), I²C bus interface, and host interface (HIF) found in higher-tier H8S/2138 variants.

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 and peripheral set, but mask ROM version (not reprogrammable); no F-ZTAT™ capability. | Suitable only for fixed-function, high-volume production where firmware never changes post-manufacture. | Select HD64F2132RV when firmware stability and lowest unit cost outweigh field update requirements. |
| H8S/2134F-ZTAT™ | 64 KB F-ZTAT™ flash, same CPU and core peripherals, but adds 3× 8-bit TMR channels (vs. 2× in DF2132RFA20V) and retains SCI/ADC/DAC compatibility. | Better suited for applications needing additional timer-based capture/compare functions without upgrading to full H8S/2138 feature set. | Choose H8S/2134F-ZTAT™ when extra 8-bit timer resources are required for encoder counting or pulse measurement alongside existing DF2132RFA20V functionality. |
Compared with HD64F2132RV, DF2132RFA20V enables field firmware updates via F-ZTAT™, while H8S/2134F-ZTAT™ extends timer capability without sacrificing flash flexibility-making DF2132RFA20V optimal for cost-sensitive, update-capable embedded controllers where minimal peripheral footprint is critical.

FAQ
What is the maximum operating frequency of the DF2132RFA20V?
The DF2132RFA20V operates at a maximum frequency of 25 MHz when supplied with 4.5 V to 5.5 V. This clock speed is supported by its H8S/2000 CPU core and defines the upper limit for instruction execution rate and peripheral timing accuracy. The DF2132RFA20V achieves this using an external crystal, ceramic resonator, or clock source connected to the EXTAL/XTAL pins, with internal PLL circuitry ensuring stable core timing.
Does the DF2132RFA20V support in-system programming of its flash memory?
Yes, the DF2132RFA20V supports in-system programming via its F-ZTAT™ (Flexible-ZTAT) 64 KB flash memory. Unlike mask ROM variants, DF2132RFA20V allows firmware updates without removing the chip from the board or applying external high-voltage programming signals. Programming is performed through the dedicated boot-mode RAM area starting at address H'(FF)E880, enabling field upgrades and production-line calibration.
How many analog-to-digital converter channels does the DF2132RFA20V have, and what is their resolution?
The DF2132RFA20V integrates an 8-channel, 10-bit successive approximation register (SAR) ADC with internal sample-and-hold circuitry. Each channel accepts analog inputs in the 0 V to VCC range and provides 10-bit digital output values (0–1023). The ADC supports software-triggered and timer-triggered conversions, making it suitable for sensor monitoring and closed-loop control applications requiring moderate precision and sampling rates up to 100 kSPS.
What communication interfaces are available on the DF2132RFA20V?
The DF2132RFA20V provides three independent Serial Communication Interface (SCI) modules, each supporting full-duplex UART operation with IrDA physical layer compatibility. These SCIs operate independently and can be configured for different baud rates, parity, and stop bits. No I²C or CAN interfaces are included-those features are reserved for higher-tier H8S/2138 devices. The SCI peripherals are mapped to dedicated port pins (e.g., P10/P11 for SCI0) and support interrupt-driven or polling-based data transfer.
What is the package type and pin count of the DF2132RFA20V?
The DF2132RFA20V is packaged in an 80-pin Thin Quad Flat Package (TQFP) with 0.5 mm lead pitch. This package provides mechanical robustness, thermal efficiency, and high I/O density suitable for compact embedded designs. All 80 pins are electrically functional-including power, ground, reset, clock, 64 general-purpose I/O lines, and dedicated peripheral signals-and match the pinout of other H8S/2132 and H8S/2134 family members for design reuse.
