Renesas DF2132FA20

Overview

DF2132FA20 from Renesas Technology Corp. is a 16-bit single-chip microcomputer in the H8S/2132F-ZTAT™ family, featuring an H8S/2000 CPU core, 64 KB on-chip flash memory (F-ZTAT™), 4 KB RAM, 8-channel 10-bit ADC, dual 2-channel 14-bit PWM timers (PWMX), and three SCI interfaces. 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 DF2132FA20 datasheet, DF2132FA20 pinout, DF2132FA20 application, or DF2132FA20 equivalent, key selection criteria include its 64 KB F-ZTAT™ flash architecture, absence of DTC/I²C/HIF modules (vs. H8S/2138), 8-bit TMR ×3, dual DAC, and FP-80A 80-pin QFP package - all confirmed for this specific variant.

Technical Context

The DF2132FA20 implements the H8S/2000 CPU core with 16×16-bit general-purpose registers, 16-Mbyte linear address space, and C-optimized instruction set. It supports single-power-supply flash programming and executes basic instructions in one state.

As a member of the H8S/2134 Group subset, it excludes DTC, I²C, HIF, and PWM (standard) modules but retains two 14-bit PWMX timers, 8-bit TMR ×3, watchdog timer ×2, SCI ×3, dual 8-bit DAC, and 8-channel 10-bit ADC with expansion inputs. Its boot area resides at H'(FF)E880–H'(FF)EFFF (1920 bytes) for 64 KB versions.

Key Specifications

Pinout & Package

DF2132FA20 is housed in an 80-pin FP-80A plastic QFP package (14 mm × 20 mm, 0.65 mm pitch), compliant with JEDEC MS-026. Pin functions are mode-dependent (single-chip, expanded, flash programmer), with dedicated pins for reset, clock input (XIN/XOUT), SCI, ADC, DAC, PWMX, and GPIO.

FAQ

What is the maximum operating frequency of the DF2132FA20?

The DF2132FA20 operates at a maximum CPU clock frequency of 25 MHz when supplied with 4.5 V to 5.5 V. This frequency is achieved using the on-chip oscillator with an external crystal (1–20 MHz range) or external clock source. The H8S/2000 core executes most instructions in a single state cycle, enabling deterministic real-time performance critical for keyboard scan timing and PWM generation in the DF2132FA20.

Does the DF2132FA20 include an I²C interface?

No, the DF2132FA20 does not include an I²C bus interface. As a member of the H8S/2134 Group subset, it omits I²C, DTC, HIF, and standard 8-bit PWM modules. Its communication peripherals are limited to three SCI interfaces (UART-compatible), which can be configured for IrDA physical layer operation. I²C functionality is present only in the higher-tier H8S/2138 Group, not in the DF2132FA20.

What is the flash memory endurance specification for DF2132FA20?

The DF2132FA20 features 64 KB of F-ZTAT™ flash memory rated for a minimum of 100 program/erase cycles and a reference value of 10,000 cycles at 25°C. Data retention is guaranteed for 10 years under specified operating conditions. These values are documented in Table 25.27 and Table 25.49 of the H8S/2138 and H8S/2134 Hardware Manual Rev. 4.00, applicable to all F-ZTAT™ variants including DF2132FA20.

How is the reset behavior configured on DF2132FA20?

The DF2132FA20 uses an active-low asynchronous RESET pin requiring a minimum assertion time of 1024 clock cycles for reliable initialization. During reset, internal registers enter defined states per the SYSCR and WSCR initial values (e.g., RAME = 1 enables RAM, HIE = 0 disables host interface). External reset is selected via the XRST bit in SYSCR, and the reset vector points to H'000000. This behavior is consistent across all H8S/2132 variants and explicitly confirmed for DF2132FA20 in Section 2.8.2 of the Hardware Manual.

Which package type is used for DF2132FA20?

The DF2132FA20 is packaged in an 80-pin FP-80A plastic quad flat package (QFP) measuring 14 mm × 20 mm with 0.65 mm lead pitch. This package is mechanically and electrically identical to the TFP-80C variant but differs in mold compound and moisture sensitivity level. Pin arrangement and thermal characteristics are fully documented in Appendix G of the Hardware Manual Rev. 4.00, confirming FP-80A as the sole package for this F-ZTAT™ flash version.
