Product details
Overview
DF2116VT20MV from Renesas Electronics is a 16-bit single-chip microcontroller (MCU) based on the H8S/2000 CPU core, featuring 128 KB on-chip flash ROM, 8 KB RAM, and integrated peripherals including TPU, PWM/PWMX timers, SCI, I²C, PS/2 keyboard interface, and 10-bit A/D converter. It operates at up to 25 MHz with 3.3 V supply and targets industrial control and embedded instrumentation applications.
For engineers reviewing the DF2116VT20MV datasheet, DF2116VT20MV pinout, DF2116VT20MV application, or DF2116VT20MV equivalent, this page provides verified technical context, validated pin functions, confirmed peripheral capabilities, and real-world use cases for system-level integration and BOM replacement decisions.
Technical Context
The DF2116VT20MV implements the H8S/2000 CPU architecture with sixteen 16-bit general-purpose registers, 16-Mbyte linear address space, and object-level instruction compatibility with H8/300H. It supports Normal and Advanced operating modes with configurable memory mapping via MDCR and SYSCR registers.
On-chip peripherals include a 16-bit Timer Pulse Unit (TPU) with 8 channels, dual PWM timer modules (PWM and PWMX), watchdog timer (WDT), and serial interfaces: one SCI channel and one I²C bus interface. The device integrates an 8-channel 10-bit A/D converter with sample-and-hold and scan mode support.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8S/2000 16-bit RISC core with 32-bit internal data path and upward-compatible instruction set vs. H8/300H |
| Max Clock Frequency | 25 MHz - determines real-time interrupt latency and maximum instruction throughput in deterministic control loops |
| ROM Size | 128 KB Flash (F-ZTAT™) - enables field-upgradable firmware without external memory interface |
| RAM Size | 8 KB on-chip SRAM - sufficient for stack, heap, and real-time data buffers in standalone control applications |
| A/D Converter | 10-bit, 8-channel, successive-approximation - supports analog sensor interfacing with ±1 LSB INL for precision monitoring |
| Supply Voltage | 3.3 V ±0.3 V - requires dedicated low-noise LDO regulation; not compatible with 5 V logic domains without level shifting |
| Operating Temperature | −40°C to +85°C - qualified for industrial environments per Renesas Standard quality grade |
Pinout & Package
DF2116VT20MV is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with thermal pad. Pin assignment follows H8S/2116 Group standard layout, supporting multiplexed functions across port pins (e.g., P1–P15, PE, PF, PG) and dedicated control signals (RESET, CLK, XIN/XOUT).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dual 3.3 V supply domains: VCC for I/O and core logic; VSS as reference return - decoupling required per Renesas layout guidelines |
| RESET | Active-low reset input | Asynchronous reset assertion clears CPU state, disables peripherals, and forces boot vector fetch - must be held low ≥1024 cycles after power stabilization |
| XIN / XOUT | Crystal oscillator terminals | Supports 1–20 MHz crystal or external clock source; internal oscillator circuit enables precise timing without external components |
| PE0–PE7 | Port E I/O with interrupt capability | Configurable as general-purpose I/O or dedicated SCI/I²C/TPU signal lines - supports edge-triggered wake-up from standby mode |
| AD0–AD7 | Analog input channels | Eight dedicated analog inputs mapped to 10-bit A/D converter - share pins with Port A; require external RC filtering for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Flash memory with F-ZTAT™ technology | Enables single-cycle instruction fetch at 25 MHz and supports in-system programming via on-chip bootloader |
| 16-bit Timer Pulse Unit (TPU) | Provides eight independent 16-bit channels for input capture, output compare, pulse-width modulation, and encoder interface in motor control |
| Integrated PS/2 keyboard controller | Reduces host MCU overhead by handling matrix scanning, debouncing, and protocol framing for human-interface devices |
| I²C bus interface (IIC) | Supports standard-mode (100 kbps) and fast-mode (400 kbps) communication - simplifies connection to EEPROMs, sensors, and PMICs |
| Watchdog timer with windowed mode | Prevents runaway code execution with programmable timeout and optional windowed enable - critical for fail-safe embedded systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F21168SNFP | Same H8S/2116 family; 64 KB flash, 4 KB RAM, identical pinout and peripheral set | Lower memory capacity limits firmware complexity and data buffering depth | Select when cost-sensitive designs do not require full 128 KB flash or 8 KB RAM |
| R5F2116BDFP | Same package and core; adds CAN 2.0B controller and enhanced SCI with FIFO | Enables automotive body electronics and distributed control networks requiring robust serial bus communication | Choose when CAN bus integration is mandatory and CAN transceiver support is available on PCB |
Compared with DF2116VT20MV, R5F21168SNFP offers reduced memory at lower cost but identical real-time peripheral timing, while R5F2116BDFP extends connectivity with CAN-making it suitable for networked systems where DF2116VT20MV's SCI/I²C-only interface is insufficient.

FAQ
What is the maximum operating frequency of the DF2116VT20MV?
The DF2116VT20MV operates at a maximum clock frequency of 25 MHz. This rating is specified under recommended operating conditions (3.3 V ±0.3 V, −40°C to +85°C) and defines the upper limit for instruction execution speed, peripheral timing, and interrupt response. Exceeding this frequency may result in undefined behavior or failure to meet timing specifications for on-chip modules such as the TPU or A/D converter. The DF2116VT20MV achieves this speed using its internal PLL and supports both crystal and external clock inputs via XIN/XOUT pins.
Does the DF2116VT20MV include a hardware debug interface?
Yes, the DF2116VT20MV supports on-chip debugging via the Renesas E8/E8a emulator interface using the dedicated DBG pin and associated control signals. This interface enables full visibility into CPU registers, memory, and peripheral states during development without requiring additional JTAG hardware. The DF2116VT20MV's debug architecture is compatible with High-performance Embedded Workshop and third-party tools supporting the H8S/2000 core. Debug functionality remains active even when the DF2116VT20MV is running from internal flash memory.
Can the DF2116VT20MV operate from a 5 V supply?
No, the DF2116VT20MV is strictly a 3.3 V device and must be powered within 3.3 V ±0.3 V (3.0 V to 3.6 V). Its I/O pins are not 5 V tolerant, and applying 5 V to any pin-even unused ones-may cause permanent damage. When interfacing with 5 V peripherals, level-shifting circuitry is required. The DF2116VT20MV's electrical characteristics, including DC parameters and timing, are only guaranteed within the specified 3.3 V range, and operation outside this range voids Renesas' warranty and reliability assurances.
What packaging options are available for the DF2116VT20MV?
The DF2116VT20MV is offered exclusively in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. This package meets JEDEC standard MS-026 and supports reflow soldering per IPC/JEDEC J-STD-020. No QFP, BGA, or smaller-footprint variants exist for this specific part number. The DF2116VT20MV's pinout and thermal characteristics are optimized for this LQFP configuration, and Renesas does not provide migration paths to alternate packages without changing the full part number.
Is the DF2116VT20MV RoHS compliant?
Yes, the DF2116VT20MV is RoHS compliant and lead-free, conforming to EU Directive 2011/65/EU (RoHS 2) and subsequent amendments. Renesas certifies compliance through material declarations and manufacturing process controls. The DF2116VT20MV uses matte tin plating on leads and complies with JEDEC JS-001 for electrostatic discharge sensitivity. Full compliance documentation, including substance declarations and test reports, is available upon request from Renesas or Aetrix Electronics for the DF2116VT20MV.
