Product details
Overview
DF2112RVLP25HV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2112R Group, featuring an H8S/2100 Series CPU core, 128 KB on-chip flash memory, 8 KB RAM, and integrated peripherals including TPU (16-bit timer pulse unit), SCI (serial communication interface), WDT (watchdog timer), and PWM output units. It operates at up to 25 MHz with 3.3 V supply voltage and supports industrial temperature range (−40°C to +85°C). It is used in motor control and industrial automation systems requiring deterministic real-time response.
For engineers reviewing the DF2112RVLP25HV datasheet, DF2112RVLP25HV pinout, DF2112RVLP25HV application, or DF2112RVLP25HV equivalent, key selection criteria include its 100-pin LQFP package, 25 MHz max clock frequency, 128 KB flash/8 KB RAM memory configuration, integrated TPU for precise timing control, and support for asynchronous and clocked synchronous serial communication via SCI.
Technical Context
The DF2112RVLP25HV implements the H8S/2100 Series CPU architecture with 16-bit data bus and 24-bit address bus, enabling direct access to up to 16 MB of memory space. It integrates a programmable clock pulse generator (CPG) supporting internal and external clock sources, and a bus controller (BSC) managing memory-mapped I/O and peripheral access timing.
Its peripheral set includes two 16-bit TPU channels with input capture, output compare, and PWM generation capabilities; one 8-bit timer (TMR); one watchdog timer (WDT); and two full-duplex SCI modules supporting asynchronous, clocked synchronous, and multiprocessor communication modes - all configurable via dedicated SFRs and interrupt vectors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8S/2100 Series 16-bit CISC core with 24-bit addressing; enables efficient real-time control code execution and direct access to large peripheral register maps. |
| Max Clock Frequency | 25 MHz; defines maximum instruction throughput and real-time peripheral timing resolution (e.g., TPU counter tick = 40 ns). |
| On-Chip Memory | 128 KB flash (program storage), 8 KB RAM (data/stack); eliminates need for external memory in compact embedded controllers. |
| Supply Voltage | 3.3 V ±0.3 V; compatible with modern low-voltage logic families and reduces power consumption vs. 5 V MCUs. |
| Operating Temperature | −40°C to +85°C; qualified for industrial environments including factory automation and motor drive cabinets. |
| I/O Pins | 81 programmable CMOS I/O pins; supports multiple peripheral functions via pin multiplexing (e.g., P44 as TMO1 or PWMU2B). |
| Interrupt Sources | 64 interrupt vectors including 32 internal (TPU, SCI, WDT) and 32 external (IRQ0–IRQ15); enables prioritized, low-latency event handling. |
Pinout & Package
DF2112RVLP25HV is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with exposed thermal pad. Pin assignments follow Renesas' standard H8S/2112R Group layout, supporting memory-mapped I/O, peripheral function multiplexing, and dedicated power/ground distribution.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated pairs per quadrant ensure stable core/peripheral voltage delivery and reduce noise coupling in mixed-signal operation. |
| CLK, EXTAL, XTAL | System clock inputs | Supports crystal oscillator (1–20 MHz) or external clock source; CLK pin drives internal CPG for synchronized peripheral timing. |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU registers, disables peripherals, and forces boot vector fetch from flash address 0x000000. |
| INT0–INT7, IRQ0–IRQ15 | External interrupt inputs | Configurable edge-sensitive inputs mapped to priority-controlled interrupt vectors; enable fast response to external events (e.g., encoder index pulse). |
| P00–P07, P10–P17, etc. | General-purpose I/O ports | 81 total CMOS bidirectional pins with individual direction control (DDR), pull-up enable, and peripheral function overlay (e.g., P44 = TMO1 or PWMU2B). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated TPU (Timer Pulse Unit) | Two independent 16-bit channels with input capture, output compare, PWM generation, and dead-time insertion - ideal for three-phase motor gate drive timing. |
| Dual SCI Modules | Each supports asynchronous UART, clocked synchronous SPI-like mode, and multiprocessor broadcast - enables robust host-to-peripheral and inter-MCU communication. |
| On-Chip Flash with Security | 128 KB flash with write-protection and security fuse; prevents unauthorized firmware readout and supports field updates without external programmer. |
| Watchdog Timer with Window Mode | Configurable timeout (1 ms–2.1 s) and windowed refresh window; detects both software hang and premature/faulty reset triggering. |
| Low-Power Modes | Four modes (HALT, STOP, WAIT, and deep standby) with selective peripheral clock gating; reduces active current to <1 mA while retaining RAM and register state. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F21128SNFP | Same H8S/2112R Group, but 64 KB flash, 4 KB RAM, and 80-pin QFP package; lacks two TPU channels and one SCI module. | Suitable for cost-sensitive, lower-I/O-count applications like simple relay controllers or basic sensor nodes. | Select when BOM cost reduction is critical and full 128 KB flash or 100-pin I/O count is unnecessary. |
| R5F21228SNFP | H8S/2200 Series successor with 25 MHz max clock, 128 KB flash, but enhanced CPG (PLL-based clock synthesis) and additional DMA channels. | Better suited for applications requiring higher peripheral bandwidth (e.g., multi-axis motion control with simultaneous ADC+PWM+SCI). | Choose for future-proof designs needing scalable performance and expanded peripheral concurrency beyond DF2112RVLP25HV's fixed resource set. |
Compared with R5F21128SNFP, DF2112RVLP25HV delivers higher memory capacity and full peripheral complement in a 100-pin footprint; versus R5F21228SNFP, it offers proven industrial maturity and simpler clock architecture at the expense of advanced features like PLL and DMA.

FAQ
What is the maximum operating frequency of the DF2112RVLP25HV?
The DF2112RVLP25HV operates at a maximum clock frequency of 25 MHz. This is achieved using either an external crystal (1–20 MHz) with internal PLL multiplication or a direct external clock source. The 25 MHz limit ensures reliable timing for all on-chip peripherals including the TPU, SCI, and WDT, and is validated across the full −40°C to +85°C industrial temperature range. DF2112RVLP25HV maintains this specification under 3.3 V ±0.3 V supply conditions.
Does the DF2112RVLP25HV support in-system programming (ISP)?
Yes, the DF2112RVLP25HV supports in-system programming via its on-chip flash memory. Firmware updates can be performed through the SCI interface using Renesas' standard bootloader protocol, eliminating the need for external programming hardware. The 128 KB flash includes sector protection and security fuse functionality to prevent unauthorized reprogramming. DF2112RVLP25HV retains full ISP capability even after soldering into the target PCB.
How many PWM output channels does the DF2112RVLP25HV provide?
The DF2112RVLP25HV provides six independent PWM output channels via its integrated Timer Pulse Unit (TPU). These are distributed across two 16-bit TPU channels (TPU0 and TPU1), each supporting up to three complementary PWM outputs with programmable dead-time insertion. DF2112RVLP25HV uses pin multiplexing (e.g., P44/P45/P46) to route these signals, enabling direct control of 3-phase inverter gate drivers without external logic.
Is the DF2112RVLP25HV qualified for automotive applications?
No, the DF2112RVLP25HV is not qualified for automotive applications. It is rated for industrial use (Standard quality grade) with operating temperature range −40°C to +85°C and is intended for applications such as motor control, PLC modules, and factory automation. Renesas specifies separate automotive-grade variants (e.g., with AEC-Q100 qualification and extended temperature range) for vehicle systems. DF2112RVLP25HV does not meet automotive reliability or qualification requirements.
What debug interface does the DF2112RVLP25HV support?
The DF2112RVLP25HV supports on-chip debugging via the Renesas E8/E8a emulator interface using the 14-pin Mictor connector. This allows full JTAG-based debugging including breakpoint setting, register inspection, and real-time variable monitoring without halting peripheral operation. DF2112RVLP25HV integrates dedicated debug control logic compliant with Renesas' standard H8S debug architecture, and requires no additional external components for emulator connection.
