Renesas DF2215RBR24V

Overview

DF2215RBR24V from Renesas Electronics is a 16-bit single-chip microcomputer in the H8S/2215R group, featuring the H8S/2000 CPU core, 256 KB on-chip flash memory (F-ZTAT™), 16 KB RAM, USB 1.1 interface, dual SCIs, 16-bit TPU, 8-bit TMR, WDT, 10-bit A/D converter (2 channels), and D/A converter. It operates at up to 24 MHz via internal PLL multiplication and targets embedded control applications requiring integrated connectivity and analog I/O.

For engineers reviewing the DF2215RBR24V datasheet, DF2215RBR24V pinout, DF2215RBR24V application, or DF2215RBR24V equivalent, key selection criteria include its 24 MHz max CPU frequency, F-ZTAT flash reprogrammability, USB 1.1 host/peripheral support, 10-bit A/D with AN0/AN1 analog inputs (requiring Vcc = AVcc), and industrial temperature range (–40°C to +85°C) compliance.

Technical Context

The DF2215RBR24V implements the H8S/2000 CPU architecture with sixteen 16-bit general-purpose registers, 32-bit internal data paths, and object-level upward compatibility with H8/300H instructions. Its system clock supports PLL-based multiplication (2× or 3×) from external crystal or oscillator inputs, enabling stable 16 MHz or 24 MHz operation.

On-chip peripherals include a direct memory access controller (DMAC), data transfer controller (DTC), USB module with CK48-ready detection, two serial communication interfaces (SCI0/SCI1) supporting asynchronous and clock-synchronous modes, and an A/D converter with sample-and-hold and conversion time of 1.2 μs (typ.) at 24 MHz φ.

FAQ

What is the maximum operating frequency of the DF2215RBR24V?

The DF2215RBR24V supports a maximum CPU operating frequency of 24 MHz, achieved using its internal PLL with 2× or 3× multiplication from an external crystal or oscillator input (e.g., 8 MHz or 12 MHz). This frequency is sustained across the full industrial temperature range (–40°C to +85°C) and supply voltage (2.7–3.6 V), enabling deterministic real-time execution in motor control and communication tasks. The DF2215RBR24V datasheet specifies timing parameters validated at this speed.

Does the DF2215RBR24V include USB functionality, and what type is supported?

Yes, the DF2215RBR24V integrates a full-speed USB 1.1 module compliant with USB Specification Rev. 1.1, supporting both device and host roles at 12 Mbps. It includes an on-chip transceiver, CK48 READY status bit for clock synchronization, and software-controlled reset (UIFRST bit in UCTLR). No external PHY or termination resistors are required, reducing system complexity. The DF2215RBR24V USB implementation is verified in Renesas' hardware manual (REJ09B0140).

What are the analog input requirements for the DF2215RBR24V's A/D converter?

The DF2215RBR24V's 10-bit A/D converter uses two dedicated pins - AN0 and AN1 - which function only when Vcc equals AVcc (i.e., digital and analog supplies must be tied together). The analog supply range is 2.7 V to 3.6 V, and the reference voltage (Vref) must be between 2.7 V and AVcc. This constraint ensures measurement accuracy and is explicitly documented in the DF2215RBR24V electrical characteristics tables (e.g., Section 26.6).

Is the DF2215RBR24V pin-compatible with other H8S/2215 variants like HD64F2215R?

No, the DF2215RBR24V is not pin-compatible with HD64F2215R or other members of the H8S/2215 family. While all share the same functional block diagram and register-level compatibility, the DF2215RBR24V uses a 120-pin TFP package, whereas HD64F2215R is offered in 112-pin BP packages. Pin counts, pitch, and physical layout differ - confirmed by Renesas' "Product-type codes and external dimensions" appendix. Board redesign is required when substituting the DF2215RBR24V.

What flash technology does the DF2215RBR24V use, and how many write/erase cycles does it support?

The DF2215RBR24V uses Renesas' F-ZTAT™ (Flash Zero Turn-Around Time) technology, a single-power 256 KB on-chip flash memory that supports in-system programming without high-voltage assist. Renesas specifies ≥10,000 write/erase cycles and data retention of 20 years at 85°C. This flash is integral to the DF2215RBR24V's design for field-upgradable firmware in industrial and test equipment applications.
