Product details
Overview
DF2144AVTE10V from Renesas Electronics is a 16-bit single-chip microcontroller in the H8S/2144 Group, featuring a 32-bit H8S/2000 CPU core, 128 KB on-chip flash memory (F-ZTAT™), 4 KB RAM, and integrated peripherals including three SCI interfaces, dual 14-bit PWM timers (PWMX), 16-bit free-running timer (FRT), watchdog timer (WDT), dual D/A converters, 8-channel 10-bit A/D converter, and I/O ports with key-scan capability - designed for intelligent power management in CD-ROM drive units and notebook PC keyboard controllers.
For engineers reviewing the DF2144AVTE10V datasheet, DF2144AVTE10V pinout, DF2144AVTE10V application, or DF2144AVTE10V equivalent, this page delivers verified technical identity, confirmed package mapping (TFP-100B), validated pin functions, real-world use context in embedded PC peripheral control, and two documented alternative parts with functional and application-level distinctions.
Technical Context
The DF2144AVTE10V 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. It operates from a single 3.0 V supply (indicated by "V" suffix) and integrates F-ZTAT™ flash for field-programmable firmware updates without external programming voltage.
Unlike the H8S/2148 Group, the DF2144AVTE10V omits the data transfer controller (DTC), I²C bus interface, host interface (HIF), PS/2 keyboard buffer controller, and 8-bit PWM timer - confirming its role as a reduced-function variant optimized for cost-sensitive, lower-peripheral-count applications such as optical drive motor control and battery monitoring subsystems.
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. |
| Flash Memory | 128 KB F-ZTAT™ flash; supports in-system reprogramming at 3.0 V, eliminating need for high-voltage programmers in production or field updates. |
| RAM | 4 KB on-chip SRAM; sufficient for stack, variables, and small real-time buffers without external memory expansion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2144AV | Same core, flash size, and pinout; differs only in packaging - HD64F2144AV uses FP-100B (standard QFP), while DF2144AVTE10V uses TFP-100B (thin fine-pitch). | FP-100B has 2.0 mm height vs. TFP-100B's 1.4 mm - impacts mechanical clearance in ultra-thin optical drives. | Select DF2144AVTE10V for space-constrained designs requiring lowest profile; HD64F2144AV where standard QFP footprint and rework compatibility are prioritized. |
| HD64F2142RV | 64 KB flash, 2 KB RAM, no PWMX, only two SCI channels, and lacks expansion A/D inputs - functionally subset of DF2144AVTE10V. | Suitable for simpler battery gauges or basic motor control without high-resolution PWM or multi-channel sensing. | Choose HD64F2142RV only when application firmware fits 64 KB and does not require dual 14-bit PWMX or 16 expansion A/D inputs - otherwise DF2144AVTE10V provides necessary headroom. |
Compared with HD64F2144AV, DF2144AVTE10V offers identical functionality in a thinner package for tighter mechanical envelopes; compared with HD64F2142RV, it delivers double flash/RAM, added PWMX resolution, and expanded analog input capability - making it the only choice for full-featured optical drive or advanced power management implementations.

FAQ
What is the core architecture of the DF2144AVTE10V?
The DF2144AVTE10V implements the 32-bit H8S/2000 CPU core with sixteen 16-bit general-purpose registers and a concise instruction set optimized for C-language efficiency. It executes basic instructions in one state and supports a 16-Mbyte linear address space - delivering deterministic real-time performance essential for motor control and keyboard scanning tasks in the DF2144AVTE10V.
Does the DF2144AVTE10V support in-system programming?
Yes, the DF2144AVTE10V features F-ZTAT™ (Flexible-ZTAT) flash memory that enables full in-system programming and erasure using only the standard 3.0 V supply - no external high-voltage programmer is required. This capability is integral to the DF2144AVTE10V's design for field-upgradable firmware in optical drives and battery management systems.
What are the key differences between DF2144AVTE10V and HD64F2144AV?
The DF2144AVTE10V and HD64F2144AV share identical electrical specifications, memory size (128 KB flash, 4 KB RAM), and peripheral sets. Their sole difference is package type: DF2144AVTE10V uses the thinner TFP-100B (1.4 mm height), while HD64F2144AV uses the standard FP-100B (2.0 mm height). Both are pin-compatible and functionally interchangeable where mechanical constraints allow.
Can the DF2144AVTE10V operate from a 3.3 V supply?
No - the "V" suffix in DF2144AVTE10V explicitly denotes 3.0 V operation (±0.3 V), and the device is not rated for 3.3 V supply. Operating outside the 2.7–3.3 V range risks functional failure or accelerated wear. For 3.3 V systems, level-shifting or regulator circuitry must be used to ensure the DF2144AVTE10V receives a compliant 3.0 V supply.
Which analog inputs are available on the DF2144AVTE10V?
The DF2144AVTE10V includes eight dedicated 10-bit A/D converter input channels (AN0–AN7) and eight expansion A/D inputs (CIN0–CIN7), accessible via Port 6 pins (P60–P67). These inputs support simultaneous sampling and are used for battery voltage monitoring, thermal sensing, and motor current feedback in DF2144AVTE10V-based designs.
