Product details
Overview
DF2211UFP24V from Renesas Electronics is a 16-bit flash microcontroller in the H8S/2212 Group, featuring 64 KB on-chip flash memory, 8 KB RAM, USB boot mode, and integrated peripherals including TPU, WDT, RTC, SCI, A/D converter, and DMAC. It operates at up to 25 MHz with 3.3 V supply and targets industrial control and embedded instrumentation applications.
For engineers reviewing the DF2211UFP24V datasheet, DF2211UFP24V pinout, DF2211UFP24V application, or DF2211UFP24V equivalent, key selection criteria include USB-based firmware update capability, 64 KB reprogrammable flash with F-ZTAT™ technology, 25 MHz max CPU clock, 3.3 V operation, and support for boundary-scan (JTAG) debugging via TMS/TCK/TDO/TDI pins.
Technical Context
The DF2211UFP24V implements the H8S/2000 CPU core with a 32-bit internal architecture, sixteen 16-bit general-purpose registers, and linear 16-Mbyte address space. It integrates a 16-bit timer pulse unit (TPU) with 8 channels, a 10-bit A/D converter with 8 inputs, and dual serial communication interfaces (SCI) supporting asynchronous and clock-synchronous modes.
Boot configuration is fixed to USB mode per its suffix "U", eliminating SCI boot option. The device supports boundary-scan testing (IEEE 1149.1) with dedicated TMS, TCK, TDO, TDI, and TRST pins - available only on TFP-100G/V and BP-112/V packages - and includes on-chip power-on reset and low-voltage detection circuits.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2211U | Same H8S/2212 Group, identical 64 KB flash, 8 KB RAM, USB boot mode, and TFP-100G package; differs only in marking (no "FP24V" suffix) | No functional difference; "FP24V" denotes specific Renesas factory programming and screening grade | Select HD64F2211U if full traceability to Renesas standard-grade industrial qualification is sufficient |
| HD64F2212U | 128 KB flash, 12 KB RAM, same USB boot mode and peripheral set; pin-compatible in TFP-100G package but requires updated memory map handling | Supports larger firmware images and more complex real-time tasks; higher memory overhead for bootloader and safety checks | Choose HD64F2212U when future firmware expansion or dual-bank OTA updates are required |
Compared with DF2211UFP24V, HD64F2211U offers identical functionality with standard Renesas marking, while HD64F2212U provides double flash/RAM capacity at the cost of increased code footprint and BOM cost - making DF2211UFP24V optimal for cost-sensitive, memory-constrained USB-boot applications.

FAQ
What is the operating voltage range for DF2211UFP24V?
The DF2211UFP24V operates at a nominal supply voltage of 3.3 V with a tolerance of ±0.3 V (3.0 V to 3.6 V). Operation outside this range may cause undefined behavior or permanent damage. The device includes an on-chip voltage detector that triggers reset below 2.7 V, ensuring safe brown-out recovery. This specification is validated per Renesas Electrical Characteristics section in the H8S/2212 Group Hardware Manual Rev.7.00.
Does DF2211UFP24V support in-circuit debugging via JTAG?
Yes, DF2211UFP24V supports IEEE 1149.1 boundary-scan debugging using the dedicated TMS, TCK, TDO, TDI, and TRST pins. These pins are fully functional in the TFP-100G package and enable full visibility into internal registers, memory, and I/O states during development. The TRST pin must be asserted low at power-on to initialize the TAP controller - a requirement explicitly documented in the Hardware Manual Section 4.3.
How does the USB boot mode work on DF2211UFP24V?
DF2211UFP24V enters USB boot mode automatically on power-up when the MD0–MD2 pins are configured for USB (per Renesas boot mode table). It enumerates as a CDC ACM device, allowing firmware upload via standard USB virtual COM port without external programmer. The process uses Renesas' proprietary protocol and requires the H8S Flash Development Toolkit. This mode is factory-locked and cannot be disabled or reconfigured to SCI boot.
What is the maximum achievable A/D conversion rate for DF2211UFP24V?
The DF2211UFP24V A/D converter achieves a maximum conversion time of 1.2 µs per 10-bit sample under optimal conditions (VCC = 3.3 V, fCLK = 25 MHz). With automatic scanning across all 8 channels, the full sequence completes in ≤9.6 µs. Conversion timing is synchronized to internal clocks and unaffected by CPU load, enabling deterministic sampling for closed-loop control applications.
Is DF2211UFP24V qualified for automotive applications?
No, DF2211UFP24V is classified as a "Standard" quality grade device per Renesas documentation and is intended for industrial, office, and consumer applications - not automotive or safety-critical systems. It lacks AEC-Q100 qualification, extended temperature screening, or failure-in-time (FIT) data required for automotive use. For automotive-grade alternatives, consult Renesas' RH850 or RL78/Auto families.
