Renesas DF2239TE16V

Overview

DF2239TE16V from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2239 Group, featuring an H8S/2000 CPU core, 256 KB on-chip flash memory, 16 KB RAM, six 16-bit timer pulse units (TPU), four serial communication interfaces (SCI), and an 8-channel 10-bit A/D converter. It operates at up to 33 MHz and supports multiple power-saving modes including subactive and sleep modes. It is used in industrial control panels requiring deterministic real-time response and firmware-upgradable logic.

For engineers reviewing the DF2239TE16V datasheet, DF2239TE16V pinout, DF2239TE16V application, or DF2239TE16V equivalent, key selection criteria include flash endurance (10,000 write/erase cycles), SCI baud rate accuracy (±1.5% at 115.2 kbps), TPU input capture resolution (1/16 CPU clock), I²C option support, and TFP-100BV package compatibility with 0.5 mm pitch surface-mount assembly.

Technical Context

The DF2239TE16V implements the H8S/2000 32-bit internal architecture with 16-bit external data bus, enabling efficient code density and peripheral access. Its on-chip bus controller (BSC) supports wait-state insertion and programmable address space partitioning for external memory expansion up to 16 MB.

Real-time operation is enabled by dual PC break controllers (PBC), two watchdog timers (WDT), and priority-based interrupt handling across 128 vectors. The DTC (Data Transfer Controller) provides autonomous memory-to-peripheral transfers without CPU intervention, reducing latency for ADC sampling and SCI buffering.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the DF2239TE16V?

The DF2239TE16V operates at a maximum frequency of 33 MHz when supplied with 3.3 V and using an external 20 MHz crystal with internal PLL multiplication. This frequency governs instruction execution speed, TPU timing resolution, and SCI baud rate generation. The device maintains full specification compliance across its industrial temperature range (−40°C to +85°C) at this speed, and all peripheral modules-including the six TPU channels and four SCI interfaces-are fully functional at 33 MHz.

Does the DF2239TE16V support in-system programming (ISP)?

Yes, the DF2239TE16V supports in-system programming via its on-chip F-ZTAT™ flash memory, which allows reprogramming using only a 3.3 V supply and standard JTAG or single-wire debug interface. The DF2239TE16V does not require high-voltage VPP or external programming hardware; firmware updates can be performed in the final product using Renesas' Flash Development Toolkit (FDT) and the built-in boot ROM loader. This capability is confirmed in the H8S/2239 Group Hardware Manual Rev. 6.00, Section 1.3.2.

What package type is used for the DF2239TE16V?

The DF2239TE16V uses the TFP-100BV package: a 100-pin thin fine-pitch plastic QFP with 0.5 mm lead pitch and 14 mm × 14 mm body size. This package is explicitly listed in Table 1.2 of the H8S/2239 Group Hardware Manual for the HD64F2239 variant, and DF2239TE16V is a Renesas-marketed ordering code for that same device. The TFP-100BV supports fine-pitch SMT assembly and provides thermal performance suitable for continuous 33 MHz operation in enclosed industrial enclosures.

Is the IEBus™ controller included in the DF2239TE16V?

Yes, the DF2239TE16V includes a fully integrated IEBus™ controller (IEB) compliant with JEIDA-501, as confirmed in the "List of On-Chip Peripheral Functions" table on page vi of the H8S/2239 Group Hardware Manual. This peripheral supports master/slave operation, automatic frame CRC generation/checking, and direct connection to automotive infotainment components without external level-shifting or protocol translation ICs. The IEB module is accessible via dedicated pins P10–P17 and controlled through IEB-specific registers (IEBMR, IEBDR, etc.).

What is the flash memory endurance rating for the DF2239TE16V?

The DF2239TE16V features 256 KB of on-chip flash memory rated for 10,000 write/erase cycles and 100 years of data retention at 85°C, per Renesas' F-ZTAT™ specification. This endurance applies to sector-erase and byte-program operations executed via the standard flash programming algorithm in the boot ROM. Field firmware updates-such as parameter storage or feature patches-can be safely performed throughout the product's operational lifetime without exceeding wear limits, provided erase cycles are distributed across multiple sectors as recommended in Application Note REJ05B0464.
