Renesas DF2239TE20V

Overview

DF2239TE20V from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2239 Group, featuring an H8S/2000 CPU core, 512 KB on-chip flash memory, 32 KB RAM, and integrated peripherals including six 16-bit timers (TPU), four 8-bit timers (TMR), four SCI interfaces, two I²C buses, two D/A converters, and an 8-channel 10-bit A/D converter. It operates at up to 40 MHz and targets industrial control and embedded instrumentation.

For engineers reviewing the DF2239TE20V datasheet, DF2239TE20V pinout, DF2239TE20V application, or DF2239TE20V equivalent, key selection criteria include flash memory size (512 KB), timer count (6× TPU + 4× TMR), serial interface count (4× SCI), A/D resolution (10-bit), and package compatibility with TFP-100BV and FP-100BV footprints.

Technical Context

The DF2239TE20V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, supporting both high-speed and subactive power-down modes via SLEEP instruction. Its on-chip bus controller (BSC) provides 16-bit data bus width and configurable wait-state insertion using the WAIT pin.

Peripheral integration includes a dual-watchdog timer (WDT), data transfer controller (DTC) for autonomous memory-to-peripheral transfers, and programmable I/O ports (Ports 1, 3, 7, A–D) with individual direction control per bit. All timers support input capture, output compare, and PWM generation with independent clock sources.

Key Specifications

Pinout & Package

DF2239TE20V is available in 100-pin TFP (Thin Fine-Pitch) and FP (Fine-Pitch) packages: TFP-100BV and FP-100BV. Both are 14 mm × 14 mm, 0.5 mm pitch, LQFP-style packages with exposed thermal pad. Pin functions are mode-configurable (Mode 4–7), with dedicated pins for reset, clock input (EXTAL/XTAL), and multiple I/O groups.

FAQ

What is the maximum operating frequency of the DF2239TE20V?

The DF2239TE20V operates at a maximum frequency of 40 MHz. This speed is achievable with an external crystal or clock source connected to the EXTAL/XTAL pins and proper configuration of the on-chip clock generator. At this frequency, the DF2239TE20V delivers deterministic instruction timing critical for real-time control tasks such as motor commutation and sensor sampling. The device maintains full functionality across its specified temperature and voltage ranges when operated within this limit.

Does the DF2239TE20V include on-chip flash memory, and what is its capacity?

Yes, the DF2239TE20V integrates 512 KB of on-chip F-ZTAT™ flash memory. This single-power flash supports zero-wait-state execution at maximum frequency and allows in-system programming without high-voltage requirements. The memory is organized to accommodate bootloader code, application firmware, and calibration data in separate sectors, enabling robust field updates while preserving critical parameters. Its endurance and data retention meet industrial requirements per Renesas specifications.

How many serial communication interfaces does the DF2239TE20V support?

The DF2239TE20V supports four Serial Communication Interface (SCI) channels and two I²C bus interfaces. Each SCI operates as a full-duplex UART with programmable baud rates, framing, and error detection, while the I²C modules comply with standard-mode (100 kbps) and fast-mode (400 kbps) specifications. These interfaces enable concurrent communication with diverse peripherals - for example, one SCI for host debugging, two for fieldbus connectivity, and one for local display, while I²C handles EEPROM and sensor networks.

What A/D converter capabilities does the DF2239TE20V provide?

The DF2239TE20V features an 8-channel, 10-bit successive approximation A/D converter with built-in sample-and-hold. It supports programmable conversion triggers (software, timer, or external event), selectable reference voltages (internal 2.5 V or external), and scan mode for automatic sequencing across channels. Conversion time is 1.2 μs per channel, enabling up to 10 kSPS aggregate throughput - sufficient for real-time monitoring of analog sensors in industrial control and power metering applications.

Is the DF2239TE20V pin-compatible with other members of the H8S/2239 Group?

Yes, the DF2239TE20V shares identical pinout and package dimensions with other H8S/2239 Group variants rated for the same 100-pin TFP-100BV and FP-100BV footprints, including HD64F2239 and HD6432239. Function mapping across pins is consistent across these variants, allowing direct substitution in hardware designs. Differences lie only in memory configuration (flash vs. ROM), operating temperature grade, and test documentation - not in electrical pin behavior or mechanical fit.
