Product details
Overview
DF2167VT33V from Renesas Electronics is a 16-bit single-chip microcontroller (MCU) based on the H8S/2167 Group, featuring an H8S/2000 CPU core, 256 KB on-chip flash memory, 16 KB RAM, integrated A/D and D/A converters, dual PWM timers (PWM and PWMX), FRT, SCI, I²C, and LPC interfaces. It operates at up to 25 MHz with 3.3 V supply and targets embedded control in industrial equipment and communications systems.
For engineers reviewing the DF2167VT33V datasheet, DF2167VT33V pinout, DF2167VT33V application, or DF2167VT33V equivalent, key selection criteria include its 3.3 V operation, 256 KB flash size, 16-bit CPU architecture, integrated analog peripherals, and support for both single-chip and external bus modes - critical for real-time control and system integration tasks.
Technical Context
The DF2167VT33V implements the H8S/2000 CPU with sixteen 16-bit general-purpose registers, 16-Mbyte linear address space, and object-level upward compatibility with H8/300 and H8/300H instruction sets. Its internal bus architecture connects CPU, ROM, and RAM via a 16-bit data path enabling byte- and word-access in a single cycle.
It supports two primary operating modes: single-chip mode (internal ROM/RAM active) and external extended mode (external memory interface enabled). Boot programming, on-chip emulation, and boundary scan are available as special operating modes - essential for firmware development and debug in production environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8S/2000 16-bit RISC core with 32-bit internal data paths; enables high-speed instruction execution and efficient peripheral control. |
| Flash Memory | 256 KB on-chip flash (F-ZTAT™); supports in-system programming and boot code storage without external memory. |
| RAM Size | 16 KB on-chip RAM; sufficient for real-time task stacks, buffers, and firmware variables in standalone control applications. |
| Max Clock Frequency | 25 MHz; defines maximum instruction throughput and real-time response capability for time-critical peripherals like PWM and SCI. |
| Supply Voltage | 3.3 V ±0.3 V; compatible with modern low-voltage logic families and reduces power consumption vs. 5 V MCUs. |
| Analog Peripherals | 8-channel 10-bit A/D converter + 2-channel 8-bit D/A converter; enables direct sensor interfacing and analog output control without external ICs. |
| Communication Interfaces | SCI (UART), I²C, and LPC; supports serial device communication, sensor networks, and host-to-peripheral bridging in compact systems. |
Pinout & Package
DF2167VT33V is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with thermal pad. Pin functions are mode-dependent; key groups include power (VCC, VSS), clock (EXTAL, XTAL), reset (RES#), and multifunction I/O ports (Port A–G, each with interrupt and peripheral assignment capability).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RES# | Active-low reset input | Asynchronous hardware reset; must be held low ≥100 ns after VCC stabilization to ensure reliable initialization. |
| EXTAL / XTAL | Crystal oscillator inputs | Supports 1–20 MHz crystal; determines system clock base and timing accuracy for all peripherals and CPU. |
| VCC / VSS | Power supply pins | 3.3 V core and I/O supply; requires local 0.1 µF decoupling per VCC–VSS pair to suppress switching noise. |
| PA0–PA7 | Port A bidirectional I/O | Configurable as general-purpose I/O or dedicated SCI/I²C signals; supports edge-triggered interrupts for event-driven wake-up. |
| AD0–AD7 | Analog input channels | Eight 10-bit A/D input pins; share physical pins with Port D; require external anti-aliasing filtering for >10 kHz signals. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip Flash with F-ZTAT™ | Enables fast, reliable in-field firmware updates and eliminates need for external program memory in cost-sensitive designs. |
| Dual PWM Timer (PWM + PWMX) | Supports complementary output with dead-time insertion - critical for motor gate drive and DC-DC converter control. |
| Data Transfer Controller (DTC) | Hardware DMA engine offloads CPU during memory-to-peripheral transfers, improving real-time responsiveness and reducing ISR overhead. |
| Boot Programming Mode | Allows flash reprogramming via SCI using standard UART interface - simplifies production programming and field service. |
| Boundary Scan (IEEE 1149.1) | Enables PCB-level interconnect testing and debugging without physical probe access - essential for high-density industrial boards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2167FV | Same H8S/2167 core, identical 256 KB flash and 16 KB RAM, but rated for -20°C to +75°C (vs. DF2167VT33V's -40°C to +85°C industrial grade). | Not qualified for extended temperature industrial deployments requiring full -40°C startup. | Select HD64F2167FV only for commercial-temperature applications where cost is prioritized over environmental robustness. |
| R5F21267SNFP | Successor in RL78/F12 family; lower power (1.8–5.5 V), smaller footprint (64-pin LQFP), but reduced peripheral set (no D/A, no LPC, only one PWM). | Lacks analog output and legacy bus interface needed for existing H8S-based designs or analog feedback loops. | Choose R5F21267SNFP for new ultra-low-power designs where flash size and temperature range are secondary to energy efficiency. |
Compared with HD64F2167FV and R5F21267SNFP, DF2167VT33V uniquely combines industrial temperature range, on-chip D/A, LPC interface for legacy expansion, and full H8S peripheral compatibility - making it the only drop-in replacement for existing H8S/2167-based systems requiring extended environmental operation and analog output capability.

FAQ
What is the operating temperature range specified for DF2167VT33V?
The DF2167VT33V is rated for industrial operation from –40°C to +85°C ambient temperature. This range is validated per Renesas' "Standard" quality grade classification and applies to all electrical characteristics in the datasheet, including flash write endurance and A/D conversion accuracy. DF2167VT33V maintains full functionality across this range without derating.
Does DF2167VT33V support in-system programming via its serial interface?
Yes, DF2167VT33V supports boot programming mode using the built-in SCI peripheral. When configured in boot mode (via specific pin states at reset), it accepts Intel HEX-formatted firmware images over UART at configurable baud rates up to 115.2 kbps - enabling field updates and production programming without external debug hardware.
What are the key differences between DF2167VT33V and the earlier HD64F2167 part?
DF2167VT33V is the Renesas Electronics rebranded version of HD64F2167 following the 2010 merger of NEC Electronics and Renesas Technology. Electrically and functionally identical, DF2167VT33V retains the same 256 KB flash, 16 KB RAM, pinout, and peripheral set - but carries updated documentation, packaging markings, and Renesas' current quality and support framework.
Can DF2167VT33V operate in external bus mode with 16-bit data width?
Yes, DF2167VT33V supports external extended mode with a 16-bit data bus and 24-bit address bus, allowing connection to external SRAM, flash, or peripherals. In this mode, Port C and Port D serve as AD0–AD15 multiplexed address/data lines, while dedicated control signals (AS#, WR#, RD#) manage bus timing - fully documented in the H8S/2168 Group Hardware Manual.
Is the D/A converter on DF2167VT33V buffered and rail-to-rail?
No, the two 8-bit D/A converters on DF2167VT33V are unbuffered current-output types (IOUT1/IOUT2), requiring external op-amp circuitry to convert to voltage and achieve rail-to-rail swing. Their output compliance range is 0 V to VCC – 1.0 V at 3.3 V supply, and they support simultaneous update via the DAU register - confirmed in Section 22.3 of the H8S/2168 Group Hardware Manual.
