Product details
Overview
DF2238RTF13V from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2238 Group, featuring an H8S/2000 CPU core, 256 KB on-chip flash memory, 16 KB RAM, and integrated peripherals including six 16-bit timer pulse units (TPU), four 8-bit timers (TMR), dual watchdog timers (WDT), four serial communication interfaces (SCI), two I²C buses, two D/A converters, and an 8-channel 10-bit A/D converter. It targets industrial control and embedded automation systems requiring deterministic real-time response.
For engineers reviewing the DF2238RTF13V datasheet, DF2238RTF13V pinout, DF2238RTF13V application, or DF2238RTF13V equivalent, key selection criteria include flash endurance (10,000 write/erase cycles), operating voltage range (3.0 V to 5.5 V), -40°C to +85°C industrial temperature grade, and TFP-100BV 100-pin LQFP package compatibility with H8S/2238R variant pin mapping.
Technical Context
The DF2238RTF13V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, supporting high-speed instruction execution at up to 33 MHz. Its on-chip bus controller (BSC) enables configurable wait-state insertion and external memory expansion up to 16 MB address space.
Peripheral integration includes a data transfer controller (DTC) for autonomous memory-to-peripheral transfers, dual PC break controllers (PBC) for hardware debugging breakpoints, and programmable I/O ports with selectable pull-up resistors and noise filter capability - all synchronized to the same clock domain for deterministic timing.

FAQ
What is the maximum operating frequency of the DF2238RTF13V?
The DF2238RTF13V supports a maximum CPU clock frequency of 33 MHz, delivering 27 MIPS performance. This frequency is achievable using an external crystal (1–20 MHz) with PLL multiplication or direct external clock input. The device maintains full specification compliance-including A/D accuracy and TPU timing-across the entire -40°C to +85°C temperature range at this speed. DF2238RTF13V's internal bus controller ensures stable memory access timing even under varying load conditions.
Does the DF2238RTF13V include hardware debug support?
Yes, the DF2238RTF13V integrates two PC break controllers (PBC) that provide hardware-assisted breakpoint and trace capabilities compliant with Renesas' E10A-USB and E20 debug interfaces. These controllers allow non-intrusive instruction tracing, conditional breakpoints, and real-time watchpoint monitoring without consuming CPU cycles. DF2238RTF13V also supports on-chip flash programming and verification via standard JTAG interface, enabling field firmware updates and secure boot validation.
What package type and pin count does the DF2238RTF13V use?
The DF2238RTF13V is supplied in a TFP-100BV 100-pin thin fine-pitch quad flat package (LQFP), measuring 14 mm × 14 mm with 0.5 mm lead pitch and an exposed thermal pad. This package is RoHS-compliant and optimized for industrial reflow profiles. Pin assignments follow the H8S/2238R variant layout, with Mode 4–7 configurations documented in Renesas Hardware Manual REJ09B0054. DF2238RTF13V shares mechanical and thermal characteristics with other TFP-100BV-marked H8S devices.
Can the DF2238RTF13V operate from a 3.3 V supply?
Yes, the DF2238RTF13V operates across a 3.0 V to 5.5 V supply range, making it fully compatible with 3.3 V logic systems. At 3.3 V, it sustains full functionality including 33 MHz operation, A/D conversion (with adjusted reference), and all peripheral interfaces. I/O pins are 5 V tolerant in input mode, allowing direct connection to legacy 5 V peripherals without level shifters. DF2238RTF13V's internal voltage regulator ensures stable core voltage regardless of supply rail fluctuations within spec.
How many serial communication interfaces does the DF2238RTF13V support?
The DF2238RTF13V integrates four independent serial communication interfaces (SCI), each supporting asynchronous full-duplex UART operation with programmable baud rates up to 2 Mbps. All four SCIs feature FIFO buffers, automatic LIN break detection, and selectable clock sources. Two additional I²C interfaces operate at standard (100 kbps) and fast (400 kbps) modes. DF2238RTF13V's SCI peripherals can be configured simultaneously for Modbus RTU, ASCII protocol, and proprietary host communication without resource conflict.
