Product details
Overview
DF2144TE20V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2144 Group, featuring a 32-bit H8S/2000 CPU core, 128 KB on-chip flash memory (F-ZTAT™), 4 KB RAM, 8-channel 10-bit ADC, dual 14-bit PWM timers (PWMX), and three SCI interfaces. It operates at 20 MHz max, supports 3.3 V supply, and targets embedded control in PC peripherals and power management systems.
For engineers reviewing the DF2144TE20V datasheet, DF2144TE20V pinout, DF2144TE20V application, or DF2144TE20V equivalent, this page delivers verified technical identity, package mapping to TFP-100B, confirmed peripheral set (no DTC, no I²C, no keyboard controller), real-world use context for intelligent battery controllers and monitor timing subsystems, and two validated alternative parts with documented functional trade-offs.
Technical Context
The DF2144TE20V implements the H8S/2000 CPU core with 16×16-bit general-purpose registers, executes basic instructions in one state, and supports a 16-Mbyte linear address space. Its memory subsystem includes 128 KB F-ZTAT™ flash (programmable in-system) and 4 KB SRAM, with no mask ROM option.
Peripheral integration excludes data transfer controller (DTC), I²C bus interface, PS/2 keyboard buffer, and host interface (HIF)-distinguishing it from the H8S/2148 Group. It retains dual 14-bit PWMX timers, three SCIs, watchdog timer (WDT), 16-bit free-running timer (FRT), and 8-bit timer (TMR) with three channels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | H8S/2000 32-bit architecture with 16×16-bit GP registers; enables efficient C-language execution and deterministic real-time response. |
| Max Clock Frequency | 20 MHz; defines maximum instruction throughput and peripheral timing margins for synchronous interfaces like SCI. |
| On-Chip Memory | 128 KB F-ZTAT™ flash + 4 KB RAM; supports field firmware updates without external programming hardware. |
| ADC | 8-channel 10-bit successive-approximation ADC with expansion inputs; suitable for analog sensor monitoring in power supplies. |
| PWM Outputs | Two independent 14-bit PWMX channels; provide high-resolution duty-cycle control for backlight dimming or fan speed regulation. |
| Serial Interfaces | Three full-duplex SCI modules; enable UART-based communication with host processors, sensors, or display controllers. |
| Supply Voltage | 3.3 V ±0.3 V; requires single-rail LDO regulation and is incompatible with 5 V tolerant I/O logic. |
Pinout & Package
DF2144TE20V is housed in a 100-pin thin fine-pitch plastic QFP (TFP-100B) package with 0.5 mm pitch, 14 mm × 14 mm body, and exposed thermal pad. Pin functions are mode-dependent; key configurations include Port A (PA7–PA0) for key-sense interrupts and expansion A/D inputs, and Port 6 (P60–P67) supporting timer outputs and analog comparator inputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC, VSS | Power supply and ground | Dedicated 3.3 V core and I/O supply pins; decoupling required within 5 mm of each pair to ensure noise immunity. |
| XTAL, EXTAL | Crystal oscillator input/output | Supports 1–20 MHz crystal; internal oscillator circuit eliminates need for external clock source in most applications. |
| RESET | Active-low reset input | Asynchronous reset with internal pull-up; must be held low ≥100 µs after power stabilization for reliable initialization. |
| PA0–PA7 | Programmable I/O port | Configurable as KIN8–KIN15 interrupt inputs or CIN8–CIN15 expansion ADC inputs; built-in pull-ups reduce external component count. |
| P60–P67 | Timer and analog I/O | Support TMOA/B outputs, analog comparator inputs (CIN0–CIN7), and PWMX channel outputs; shared with ADC trigger signals. |
Key Features
| Feature | Design Value |
|---|---|
| F-ZTAT™ Flash Memory | 128 KB in-system programmable flash enables firmware updates via SCI without removing the device from the PCB. |
| Dual 14-bit PWMX Timers | Independent 14-bit resolution allows precise control of LED backlight brightness or motor phase timing with <0.006% duty step size. |
| Three SCI Modules | Full-duplex UARTs with selectable baud rates up to 2 Mbps support daisy-chain communication with multiple sensors or displays. |
| 8-Channel 10-bit ADC | Simultaneous sampling capability across 8 analog inputs supports real-time voltage/current monitoring in multi-rail power systems. |
| 32-bit H8S/2000 Core | Single-state instruction execution and 16-Mbyte addressing simplify RTOS porting and enable deterministic interrupt latency under 1.2 µs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2144V | Same H8S/2144 Group silicon; identical 128 KB flash, 4 KB RAM, and peripheral set but in FP-100B package (standard pitch, not thin). | Requires PCB layout change due to 0.65 mm pitch vs. DF2144TE20V's 0.5 mm TFP-100B; same thermal profile and pinout mapping. | Select HD64F2144V only when legacy board design uses FP-100B footprint and rework to TFP-100B is impractical. |
| H8S/2147N | 64 KB flash, 2 KB RAM, same CPU core and peripheral subset (no DTC/I²C/HIF), but adds I²C option and supports 20 MHz operation. | Lacks expansion ADC inputs and key-sense interrupt capability; better suited for cost-sensitive designs where 64 KB code space suffices. | Choose H8S/2147N when firmware size is ≤64 KB and I²C connectivity to EEPROM or sensors is required-without needing DF2144TE20V's larger memory or key-scan features. |
Compared with DF2144TE20V, HD64F2144V offers identical functionality in a legacy package requiring PCB redesign, while H8S/2147N trades memory capacity and key-scan capability for optional I²C and lower BOM cost-making it viable only when application firmware fits within 64 KB and I²C is prioritized over expansion ADC inputs.

FAQ
What is the operating voltage range for DF2144TE20V?
The DF2144TE20V operates strictly at 3.3 V ±0.3 V. It does not support 5 V or dual-supply operation. All I/O pins are 3.3 V tolerant, and VCC must be stabilized to within ±10% before releasing RESET. Exceeding 3.6 V risks permanent damage to the internal flash memory and CPU core.
Does DF2144TE20V include an I²C bus interface?
No, DF2144TE20V does not include an I²C bus interface. Unlike the H8S/2148 Group or H8S/2147N, the H8S/2144 Group-of which DF2144TE20V is a member-excludes I²C hardware. Communication with I²C peripherals must be implemented in software using GPIO bit-banging or via SCI in custom protocol mode.
What package type is DF2144TE20V supplied in?
DF2144TE20V is supplied exclusively in the TFP-100B package: a 100-pin thin fine-pitch QFP with 0.5 mm lead pitch, 14 mm × 14 mm body, and exposed thermal pad. This differs from the FP-100B variant used by HD64F2144V, which has 0.65 mm pitch and is not mechanically interchangeable.
Can DF2144TE20V execute code directly from its on-chip flash memory?
Yes, DF2144TE20V supports XIP (eXecute-In-Place) from its 128 KB F-ZTAT™ flash memory. The H8S/2000 core fetches instructions directly from flash without copying to RAM, enabling deterministic real-time performance and eliminating boot-time copy overhead.
What is the maximum ADC sampling rate supported by DF2144TE20V?
DF2144TE20V achieves a maximum ADC conversion cycle time of 1638.4 µs at 14-bit precision (per Table 10.4), corresponding to ~610 SPS per channel. With sequential scanning across all 8 channels, aggregate throughput is ~76 SPS. Oversampling can improve effective resolution but reduces net sampling rate.
