Product details
Overview
DF2630UF16LV from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2600 Series, featuring an on-chip H8S/2600 CPU core, 128 KB mask ROM, 8 KB RAM, 16-bit timer pulse unit (TPU), serial communication interface (SCI), 10-bit A/D converter with 12 channels, and motor control PWM timer. It targets industrial motor control and embedded automation systems requiring deterministic real-time response.
For engineers reviewing the DF2630UF16LV datasheet, DF2630UF16LV pinout, DF2630UF16LV application, or DF2630UF16LV equivalent, key selection criteria include its mask-ROM-based firmware permanence, 48 MHz max CPU clock, integrated DTC for zero-CPU-load data transfers, and support for subclock modes (subactive/subsleep/watch) in U-mask variants like this one.
Technical Context
The DF2630UF16LV implements the H8S/2600 CPU architecture with 32-bit internal data paths and 16-bit external bus interface. It integrates a programmable pulse generator (PPG), watchdog timer unit (WDT), and PC brake controller - all confirmed functional per H8S/2630 Group specifications.
Its peripheral set includes a data transfer controller (DTC) supporting memory-to-peripheral and peripheral-to-memory transfers without CPU intervention, and SCI modules compatible with RS-232/RS-485 protocols via external level shifters. Subclock oscillator functionality is enabled in the U-mask version, allowing low-power operation down to 32.768 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8S/2600 16-bit RISC core with 32-bit internal ALU and 16-bit external bus |
| ROM Type & Size | 128 KB mask ROM - firmware permanently embedded, no field reprogramming |
| RAM Size | 8 KB on-chip RAM - sufficient for real-time task stacks and I/O buffers |
| Max Operating Frequency | 48 MHz CPU clock - enables 12.5 ns instruction cycle time for deterministic timing |
| A/D Converter | 10-bit SAR ADC with 12 input channels - supports analog sensor acquisition in motor feedback loops |
| Timer Resources | 16-bit TPU with 8 channels + PWM timer - provides precise phase-shifted PWM outputs for 3-phase inverter control |
| DTC Support | Data Transfer Controller with 8 channels - offloads ADC-to-memory or UART-to-buffer transfers from CPU |
Pinout & Package
DF2630UF16LV is housed in a 128-pin FP-BGA (Fine-Pitch Ball Grid Array) package with 0.8 mm pitch, designed for high-density industrial PCB layouts and thermal reliability under continuous operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply / Ground | Dual 5 V supply domains: VCC for I/O and core logic, VSS as common reference plane |
| RES | Reset input | Active-low asynchronous reset - initiates hardware initialization sequence on falling edge |
| MD0–MD2 | Mode select inputs | Configure boot mode: MD2=0, MD1=1, MD0=0 selects normal mask-ROM execution mode |
| PF0–PF7 | Port F I/O | Configurable 8-bit port with alternate functions including TPU output, SCI signals, and subclock oscillator pins OSC1/OSC2 |
| TxD1 / RxD1 | SCI channel 1 serial I/O | Full-duplex UART interface - supports baud rates up to 2 Mbps with programmable prescaler |
Key Features
| Feature | Design Value |
|---|---|
| Subclock oscillator support | Enables subactive/subsleep/watch modes using external 32.768 kHz crystal - reduces standby current to <10 µA |
| Integrated PC brake controller | Hardware-assisted emergency stop logic for motor drives - asserts brake signal within ≤2 µs of fault detection |
| Programmable pulse generator (PPG) | Generates complementary PWM waveforms with dead-time insertion - eliminates software timing jitter in inverter gate drive |
| I²C bus interface option | Available only in W-mask versions; not implemented in DF2630UF16LV (U-mask) - confirms absence of I²C pins |
| FWE pin function | No-connect (NC) in mask ROM versions - must be left open or tied to VSS per hardware manual guidance |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| H8S/2630F20 | Same core and peripherals but uses flash memory (128 KB) instead of mask ROM - supports field firmware updates | Preferred where design iteration or post-deployment bug fixes are required; lacks subclock oscillator support | Select H8S/2630F20 if firmware update capability outweighs the need for ultra-low-power watch mode operation |
| H8S/2638F20 | Higher integration: adds PPG, DTC, and PC brake controller - matches DF2630UF16LV feature set but in flash variant | Targets same motor control use cases but requires external flash programming infrastructure and higher BOM cost | Choose H8S/2638F20 only when flash-based development flexibility justifies added complexity and cost |
Compared with H8S/2630F20 and H8S/2638F20, DF2630UF16LV trades field-programmability for guaranteed firmware immutability and subclock-enabled ultra-low-power modes - making it optimal for cost-sensitive, high-volume industrial controllers with fixed-function requirements.

FAQ
What is the ROM type used in DF2630UF16LV and how does it affect firmware updates?
DF2630UF16LV uses 128 KB mask ROM, meaning firmware is permanently embedded during wafer fabrication and cannot be modified post-manufacture. This guarantees code integrity and eliminates risk of corruption but precludes field updates. For DF2630UF16LV, firmware changes require a new silicon revision - making it ideal for mature, high-volume applications where functionality is fully validated and stable.
Does DF2630UF16LV support subclock oscillator functionality, and which pins are involved?
Yes, DF2630UF16LV (U-mask version) supports subclock oscillator functionality for subactive, subsleep, and watch modes. Pins OSC1 and OSC2 on Port F are dedicated to this 32.768 kHz crystal interface. The hardware manual specifies fixed pin configurations for these signals in U-mask devices, enabling ultra-low-power operation with typical standby current below 10 µA.
Is the Data Transfer Controller (DTC) available in DF2630UF16LV, and what transfer types does it support?
Yes, DF2630UF16LV includes a full-featured Data Transfer Controller (DTC) with eight independent channels. It supports memory-to-peripheral, peripheral-to-memory, and memory-to-memory transfers - including automatic chaining and interrupt-on-completion. In DF2630UF16LV, the DTC is confirmed operational per the H8S/2630 Group hardware manual and relieves the CPU from ADC buffer management and SCI transmit/receive operations.
What are the key differences between DF2630UF16LV and the H8S/2635 Group devices?
DF2630UF16LV belongs to the H8S/2630 Group and includes PPG, DTC, PC brake controller, and subclock support - all absent in the H8S/2635 Group. The H8S/2635 lacks DTC, PPG, and I²C interface, and does not support subclock modes. These omissions make DF2630UF16LV uniquely suited for advanced motor control, while H8S/2635 targets simpler, lower-cost applications.
Can DF2630UF16LV operate in CAN bus applications, and what hardware support exists?
No, DF2630UF16LV does not integrate a CAN controller. The H8S/2630 Group lacks HCAN modules entirely - unlike the H8S/2638 or H8S/2639 Groups which include HCAN1. For CAN-based designs, DF2630UF16LV requires external CAN transceivers paired with its SCI interface (e.g., using SCI in UART-to-CAN bridge firmware), but native CAN protocol handling is not supported in DF2630UF16LV.
