Product details
Overview
DF2161BVT10V from Renesas Electronics is a 16-bit H8S/2161B microcontroller featuring an H8S/2000 CPU core, 128 KB on-chip Flash ROM (F-ZTAT™), 4 KB RAM, and integrated peripherals including 10-bit ADC, 8-bit DAC, SCI, I²C, PWM timers (8-bit and 14-bit), FRT, WDT, DTC, and X-bus/LPC host interfaces. It targets embedded control in industrial instrumentation and legacy system upgrades.
For engineers reviewing the DF2161BVT10V datasheet, DF2161BVT10V pinout, DF2161BVT10V application, or DF2161BVT10V equivalent, key selection criteria include its 128 KB reprogrammable Flash memory, 48-MHz max CPU clock, 100-pin LQFP package with X-bus interface support, and qualification for Standard-grade applications per Renesas quality classification.
Technical Context
The DF2161BVT10V implements the H8S/2000 32-bit internal architecture with sixteen 16-bit general-purpose registers and a linear 16-Mbyte address space. Its CPU supports high-speed instruction execution via an optimized RISC-like instruction set and includes condition-code register (CCR) with interrupt mask bits (I/UI) enabling three-level priority interrupt control.
On-chip peripheral integration centers on system-level connectivity: the X-bus interface supports DRAM expansion, while the LPC interface enables legacy PC-compatible host communication. The DTC operates as a bus master for autonomous data transfers, reducing CPU overhead during memory-to-peripheral operations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HD64F2160BV | 64 KB Flash ROM, same 4 KB RAM, identical pinout and peripheral set | Lower code storage capacity limits complex protocol stacks or large lookup tables | Select when firmware size remains under 64 KB and cost sensitivity outweighs field-upgrade flexibility |

FAQ
What is the maximum operating frequency of the DF2161BVT10V?
The DF2161BVT10V supports a maximum CPU clock frequency of 48 MHz, achieved using an external crystal or oscillator connected to the EXTAL/XTAL pins. This frequency defines the upper bound for instruction execution speed and peripheral timing resolution. The DF2161BVT10V's H8S/2000 core maintains deterministic timing at this rate, making it suitable for hard real-time control loops in industrial applications.
Does the DF2161BVT10V include on-chip Flash memory, and is it reprogrammable?
Yes, the DF2161BVT10V integrates 128 KB of on-chip F-ZTAT™ Flash memory, which is fully reprogrammable in-system without requiring UV erasure or device removal. This capability allows firmware updates in deployed equipment - a key advantage for DF2161BVT10V in field-serviceable industrial controllers and instrumentation systems.
Which host interface protocols does the DF2161BVT10V support?
The DF2161BVT10V supports two host interface protocols: the X-bus interface for connecting to DRAM, SRAM, and peripheral chips, and the Low Pin Count (LPC) interface compliant with Intel LPC 1.1 specifications. Pins P80 (PME#), P82 (CLKRUN#), and P83 (LPCPD) are dedicated to LPC signaling, enabling DF2161BVT10V to function as a slave device in PC-attached embedded systems.
What analog peripherals are integrated into the DF2161BVT10V?
The DF2161BVT10V integrates an 8-channel 10-bit successive-approximation A/D converter and a single-channel 8-bit D/A converter. The ADC accepts inputs referenced to AVCC/AVSS and supports software/start-triggered conversions; the DAC provides a buffered voltage output (DA0) usable for calibration references or analog actuator control - both reduce external component count in DF2161BVT10V-based designs.
Is the DF2161BVT10V qualified for automotive or safety-critical applications?
No, the DF2161BVT10V is classified as a Standard-grade Renesas product, intended for applications such as industrial robots, office equipment, and test instrumentation. It is not qualified for automotive, medical life-support, or aerospace use. Customers requiring DF2161BVT10V in high-reliability domains must obtain prior written consent from Renesas Electronics and perform full system-level safety validation.
