Product details
Overview
DF2319CVTE25V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2319 Group, featuring an H8S/2000 CPU core, 256 KB on-chip flash memory (F-ZTAT™), 16 KB RAM, and integrated peripherals including 16-bit TPU, SCI, A/D and D/A converters, watchdog timer, and DTC. It operates at up to 25 MHz and targets embedded control systems requiring reprogrammable firmware and mixed-signal interfacing.
For engineers reviewing the DF2319CVTE25V datasheet, DF2319CVTE25V pinout, DF2319CVTE25V application, or DF2319CVTE25V equivalent, key selection criteria include its 25 MHz max clock frequency, 256 KB flash endurance (≥100 write/erase cycles), 10-year data retention, 10-bit A/D with 8 channels, and support for software standby and module stop power modes.
Technical Context
The DF2319CVTE25V implements the H8S/2000 32-bit internal architecture with 16-bit external bus interface, enabling high-level control tasks while maintaining code efficiency. Its peripheral set includes a 16-bit timer pulse unit (TPU) with input capture/output compare, asynchronous serial communication interface (SCI) supporting UART mode, and a 10-bit successive-approximation A/D converter with sample-and-hold.
Power management is handled via five operating modes - high-speed, medium-speed, sleep, module stop, and software/hardware standby - each with distinct clock gating and register retention behavior. Flash memory programming uses command-based on-board erasure (block-wise) and 128-byte programming, with hardware/software protection modes preventing unintended writes.
Key Specifications

Pinout & Package
DF2319CVTE25V is housed in a 113-pin LQFP (14 mm × 20 mm, 0.65 mm pitch) package, designated TLP-113V per Renesas documentation. Pin functions are defined across 8 I/O ports (P1–P7, PA–PG), with dedicated pins for reset, clock input (XIN/XOUT), VCC/VSS rails, and peripheral signals including TPU, SCI, A/D, D/A, and chip select lines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Separate analog/digital power domains ensure noise isolation for A/D and D/A operation. |
| XIN / XOUT | Crystal oscillator input/output | Supports external crystal (1–20 MHz) or ceramic resonator; required for precise timing in communication and control loops. |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; initiates CPU and peripheral initialization sequence. |

| DA0 / DA1 | Digital-to-analog outputs | 2 independent 8-bit voltage-output DACs; used for programmable reference generation or analog actuator drive. |
| TPU0–TPU7 | Timer pulse unit I/O | 8 dedicated pins for input capture, output compare, PWM generation, and encoder interface. |
| SCIS0 / SCIR0 | SCI channel 0 transmit/receive | Full-duplex UART interface with programmable baud rate; supports host MCU communication or sensor telemetry. |
Key Features
| Feature | Design Value |
|---|---|
| Reprogrammable Flash Memory | F-ZTAT™ technology enables ≥100 on-board erase/write cycles without external programmer, supporting firmware updates in production and field. |
| Integrated Mixed-Signal Peripherals | On-chip 10-bit A/D (8 ch), 8-bit D/A (2 ch), and 16-bit TPU eliminate need for external signal conditioning ICs in motor control and sensor systems. |
| Multi-Level Power Management | Five operating modes with selective peripheral clock gating reduce active current to <10 mA and standby current to <10 μA. |
| Hardware Protection Modes | Three-tier flash protection (software register lock, hardware reset/standby disable, error detection) prevents accidental or malicious firmware corruption. |
| Programmable Serial Interface | SCI supports asynchronous UART mode with programmable bit rate (e.g., 9600 bps @ 25 MHz with 0.47% error), enabling reliable host diagnostics and configuration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F2319CDFA | Same H8S/2319 Group, 100-pin QFP package, 256 KB flash, but rated for industrial temperature range (−40°C to +85°C) vs. DF2319CVTE25V's standard grade (0°C to +70°C). | Suitable for extended ambient environments where thermal stability is critical, e.g., outdoor industrial enclosures. | Select R5F2319CDFA when operating temperature exceeds 70°C or when board layout requires smaller footprint (100-pin vs. 113-pin). |
| H8S/2218 | Legacy H8S/2200 Series part with 128 KB flash, no on-chip D/A, lower max clock (20 MHz), and fewer TPU channels (4 vs. 8). | Limited to simpler control tasks without analog output requirements or high-resolution timing. | Choose H8S/2218 only for cost-sensitive legacy designs where flash size, DAC, and TPU channel count are non-critical. |
Compared with DF2319CVTE25V, R5F2319CDFA offers wider temperature tolerance in a smaller package but identical core functionality, while H8S/2218 sacrifices flash capacity, analog output capability, and timer resources-making it unsuitable for applications relying on DF2319CVTE25V's full peripheral set.

FAQ
What is the maximum operating frequency of the DF2319CVTE25V?
The DF2319CVTE25V supports a maximum system clock frequency of 25 MHz, achieved using an external crystal or resonator connected to the XIN/XOUT pins. This frequency determines instruction execution speed and timing resolution for peripherals such as the TPU and SCI. The device maintains full electrical specifications-including A/D conversion accuracy and flash programming timing-at this rated speed, as confirmed in Renesas' Hardware Manual Rev.7.00.
Does the DF2319CVTE25V include on-chip debug capability?
Yes, the DF2319CVTE25V supports on-chip debugging via the on-chip debug interface (OCD), compatible with Renesas' E8/E8a emulators and High-performance Embedded Workshop IDE. This enables real-time register inspection, breakpoint setting, and memory access during development-without requiring external JTAG hardware. The DF2319CVTE25V debug features are fully documented in the H8S/2319 Group Hardware Manual and require no additional silicon beyond the standard part.
What are the flash memory programming requirements for DF2319CVTE25V?
DF2319CVTE25V flash programming requires on-board command execution in user program mode, with minimum 10 ms per 128-byte write and 50 ms per block erase. Programming must be initiated from on-chip RAM, and all flash protection modes (software/hardware/error) must be disabled beforehand. The DF2319CVTE25V does not require external high-voltage programming signals-standard VCC suffices-and supports in-system updates via SCI or parallel interface as described in Section 17 of the Hardware Manual.
Can DF2319CVTE25V operate in low-power modes while retaining RAM contents?
Yes, DF2319CVTE25V retains full 16 KB RAM contents in both software standby mode and module stop mode. In software standby, CPU and most clocks halt while RAM and selected registers remain powered; in module stop, individual peripheral clocks can be gated independently. Both modes draw sub-100 μA current with RAM retention enabled, making DF2319CVTE25V suitable for battery-powered applications requiring fast wake-up and state preservation.
Is the DF2319CVTE25V qualified for automotive applications?
No, the DF2319CVTE25V is classified as a "Standard" quality grade device per Renesas' quality grading system and is intended for applications including office equipment, communications gear, and industrial robots-not automotive or safety-critical systems. It lacks AEC-Q100 qualification, extended temperature range certification, or fault-tolerant design features required for automotive use. For automotive-grade alternatives, consult Renesas' RH850 or RL78 families instead of the DF2319CVTE25V.
