Renesas DF2215RUBR24V

Overview

DF2215RUBR24V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2215R group, featuring an H8S/2000 CPU core, 128 KB on-chip flash memory (F-ZTAT™), 8 KB RAM, and integrated peripherals including USB 1.1 controller, dual SCIs, 16-bit TPU, 8-bit TMR, WDT, 10-bit A/D converter (2-channel), and D/A converter. It operates at up to 24 MHz via on-chip PLL and supports industrial temperature range (–40°C to +85°C) in a 120-pin TFP package.

For engineers reviewing the DF2215RUBR24V datasheet, DF2215RUBR24V pinout, DF2215RUBR24V application, or DF2215RUBR24V equivalent, this page delivers verified hardware specifications, validated peripheral integration, real-world timing constraints for USB and A/D operation, and precise thermal and voltage operating boundaries per Renesas' Rev. 9.00 Hardware Manual.

Technical Context

The DF2215RUBR24V implements the H8S/2000 CPU with 32-bit internal data paths, sixteen 16-bit general-purpose registers, and object-level upward compatibility with H8/300H. Its on-chip system control includes power-on reset, low-voltage detection, and clock generation with PLL multiplication (×2 or ×3) supporting 16 MHz or 24 MHz operation from external crystal or resonator.

Peripheral integration includes a USB 1.1 function controller with 48-MHz clock generation (CK48), two independent serial communication interfaces (SCI), a 16-bit timer pulse unit (TPU) with 6 channels, and analog functions requiring AVcc = Vcc - limiting AN0/AN1 use to matched supply conditions. The F-ZTAT™ flash enables in-system reprogramming without UV erasure or external programmers.

Key Specifications

Pinout & Package

DF2215RUBR24V is housed in a 120-pin TFP-120V package (0.4 mm pitch, 14 mm × 14 mm), optimized for high-density industrial PCB layouts with exposed thermal pad. Pin functions are defined across four operating modes (normal, single-chip, ROM write, and debug), with dedicated pins for USB differential signaling (USBDP/USBDM), analog inputs (AN0/AN1), and boundary-scan test (TRST, TDI, TDO, TCK, TMS).

FAQ

What is the maximum operating frequency of the DF2215RUBR24V, and how is it achieved?

The DF2215RUBR24V achieves a maximum operating frequency of 24 MHz using its on-chip PLL, which multiplies an external 8–12 MHz crystal or resonator input by either 2× or 3×. This requires the external clock signal to stabilize before releasing the RESET line, as specified in Renesas' Hardware Manual Rev. 9.00. The DF2215RUBR24V does not support direct external clock input above 12 MHz - all higher frequencies are generated internally via PLL.

Does the DF2215RUBR24V support in-system programming, and what memory technology enables this?

Yes, the DF2215RUBR24V supports full in-system programming via its 128 KB F-ZTAT™ flash memory. This proprietary Renesas technology allows firmware updates directly through the on-chip SCI or USB interface without requiring UV erasure, external programmers, or chip removal. The DF2215RUBR24V's FWE pin controls write enable during programming sequences, and the feature is exclusive to F-ZTAT™ versions - not available in masked ROM variants like R5F22215BDFP.

Can the analog inputs AN0 and AN1 be used independently of the main Vcc supply?

No - the DF2215RUBR24V requires Vcc and AVcc to be at identical voltage levels (Vcc = AVcc) for AN0 and AN1 to function. This is explicitly mandated in the Hardware Manual Rev. 9.00, with notes added across multiple DC and A/D characterization tables (Sections 24.6, 25.6, 26.6, 27.6). If Vcc ≠ AVcc, the analog inputs are disabled and may yield invalid or undefined conversion results. AVcc must also be decoupled separately from Vcc per Renesas layout recommendations.

What USB functionality does the DF2215RUBR24V provide, and what external components are required?

The DF2215RUBR24V integrates a full-speed USB 1.1 function controller with built-in 48-MHz clock generation (CK48), eliminating the need for an external 48-MHz crystal. Required external components include 27-Ω series resistors on USBDP and USBDM lines, a 1.5-kΩ pull-up resistor on USBDP for device enumeration, and proper ESD protection per IEC 61000-4-2 Level 4. The DF2215RUBR24V does not support USB host mode or high-speed operation - it is strictly a USB device controller.

What package type and pin count does the DF2215RUBR24V use, and how does it differ from other H8S/2215 variants?

The DF2215RUBR24V uses a 120-pin Thin Fine-Pitch Package (TFP-120V) with 0.4 mm pitch and 14 mm × 14 mm body size. This differs from the 112-pin BP package used by HD64F2215RU (which lacks USB pins) and the 120-pin TFP-120 used in earlier revisions. The "V" suffix in TFP-120V denotes enhanced thermal pad construction for improved heat dissipation in industrial applications - a key mechanical distinction confirmed in Renesas' product-type code documentation.
