Renesas DF2630F20V

Overview

DF2630F20V from Renesas Electronics is a 16-bit single-chip microcontroller 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, watchdog timer (WDT), and motor control PWM timer. It operates at up to 20 MHz and targets industrial control systems requiring deterministic real-time response.

For engineers reviewing the DF2630F20V datasheet, DF2630F20V pinout, DF2630F20V application, or DF2630F20V equivalent, this page provides verified hardware specifications, validated peripheral integration details, confirmed package mapping to FP-128B, and two documented alternative parts for functional substitution in embedded control designs.

Technical Context

The DF2630F20V implements the H8S/2600 CPU core with 32-bit internal data path and 16-bit external bus interface. It supports five operating modes (Modes 0–4) controlled by MD0–MD2 pins and includes dedicated hardware modules: TPU with 8 channels, SCI with full-duplex asynchronous operation, and a 12-channel 10-bit successive-approximation A/D converter with sample-and-hold.

It integrates a programmable pulse generator (PPG), PC brake controller, and internal data transfer controller (DTC) - all confirmed active in the H8S/2630 Group per Hardware Manual Rev.8.00. The device uses mask ROM (not flash), rendering FWE pin NC and requiring VSS tie-down per Section 1.3.1.

Key Specifications

FAQ

What is the ROM type used in DF2630F20V and how does it affect firmware updates?

DF2630F20V uses mask ROM, not flash memory. This means firmware is permanently programmed during wafer fabrication and cannot be field-updated. The FWE pin is NC and must be tied to VSS. Mask ROM ensures zero risk of corruption, guaranteed data retention over 15+ years, and eliminates boot-time verification overhead - ideal for safety-critical or maintenance-free deployments where firmware stability outweighs update flexibility.

Does DF2630F20V support CAN bus communication?

No, DF2630F20V does not include a CAN controller. The H8S/2639F20V variant adds HCAN1 support, but DF2630F20V lacks CAN-related registers (BCR, TXPR, ABACK), dedicated CAN pins, and associated module stop control bits (MSTPC2). For CAN-based designs, H8S/2639F20V is the direct family alternative - DF2630F20V requires external CAN transceivers and software-managed protocols if serial bus communication is needed.

What is the maximum operating frequency and corresponding supply voltage range for DF2630F20V?

DF2630F20V operates at a maximum frequency of 20 MHz with a supply voltage range of 4.5 V to 5.5 V. Electrical characteristics in the Hardware Manual specify that AC timing parameters (e.g., TPU pulse width, A/D conversion time) are guaranteed only within this voltage and frequency envelope. Operation outside these limits may cause timing violations, reduced noise margin, or failure to meet specified interrupt latency guarantees.

How many A/D input channels does DF2630F20V have, and what is their resolution and sampling capability?

DF2630F20V features 12 dedicated A/D input channels (AN0–AN11) with 10-bit resolution using a successive-approximation architecture. It supports single-ended or differential input configurations, programmable sample-and-hold timing, and hardware triggering from TPU or PPG events - enabling synchronized multi-channel sampling at up to 100 kSPS aggregate rate under optimal conditions.

Is the Data Transfer Controller (DTC) available in DF2630F20V, and what peripherals can it serve?

Yes, DF2630F20V includes the on-chip Data Transfer Controller (DTC), confirmed active per Hardware Manual Rev.8.00 Section 1.4 and Figure 1-3. It supports automatic data movement between A/D result registers, SCI transmit/receive buffers, and RAM without CPU involvement. Valid sources/destinations include ADARx, TDR, RDR, and general RAM addresses - reducing CPU load during high-throughput sensor logging or serial streaming tasks.
