Overview
UPD70F3611M2GBA-GAH-AX from NEC Electronics is a 32-bit V850ES/FF3 single-chip microcontroller featuring 128 KB on-chip Flash memory, 80-pin QFP package, 32 MHz max CPU clock, integrated CAN 2.0B controller, and 10-bit A/D converter with 16 channels. It targets industrial motor control and embedded automation systems requiring real-time I/O handling and deterministic communication.
For engineers reviewing the UPD70F3611M2GBA-GAH-AX datasheet, UPD70F3611M2GBA-GAH-AX pinout, UPD70F3611M2GBA-GAH-AX application, or UPD70F3611M2GBA-GAH-AX equivalent, key selection considerations include its A-grade industrial temperature range (−40°C to +85°C), EVDD-supplied I/O groups, dual-clock domain support (main/sub system clocks), and SuperFlash®-based Flash endurance (100k write/erase cycles).
Technical Context
The UPD70F3611M2GBA-GAH-AX implements the V850ES CPU core with Harvard architecture, supporting 32-bit integer operations and 16-bit compressed instruction set. Its clock system integrates a main crystal oscillator (4–16 MHz), sub-system RC oscillator (32 kHz), PLL for CPU clock multiplication, and SSCG for EMI reduction.
It features dedicated peripheral domains: EVDD-powered general-purpose I/O (Groups 1x/2x/6), AVREF0-referenced analog inputs (Group 4), and VRO-supplied crystal terminals (Group 7). The device includes POC (Power-On Clear), LVI (Low-Voltage Interrupt), and RAM retention flag functionality for robust power management in industrial environments.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Renesas RL78/F13 | 16-bit core, 128 KB Flash, 32 MHz max, integrated CAN; lower DMIPS/MHz than V850ES but enhanced low-power modes. | Targeted at ultra-low-power sensor nodes and battery-backed controllers where active current <100 µA is critical. | Select RL78/F13 when energy efficiency outweighs raw computational throughput; verify CAN timing compatibility for legacy network integration. |
| Infineon XC2000 family (e.g., XC2267) | 32-bit C166-derived core, 256 KB Flash, 80 MHz, dual CAN, higher peripheral integration (e.g., CAPCOM6). | Designed for automotive powertrain and chassis control; includes ASIL-B ready safety mechanisms not present in UPD70F3611M2GBA-GAH-AX. | Choose XC2267 for safety-critical applications requiring ISO 26262 compliance; avoid if industrial A-grade qualification and cost sensitivity are primary drivers. |
Compared with RL78/F13 and XC2267, UPD70F3611M2GBA-GAH-AX offers balanced performance for deterministic industrial control with proven Flash reliability and simpler toolchain support, while avoiding automotive-grade overhead or ultra-low-power compromises.

FAQ
What is the maximum operating frequency of the UPD70F3611M2GBA-GAH-AX CPU core?
The UPD70F3611M2GBA-GAH-AX supports a maximum CPU clock frequency (fVBCLK) of 32 MHz. This requires VDD ≥ 4.0 V; at 3.3 V ≤ VDD < 4.0 V, only core functions (CPU, Flash, RAM, I/O buffer, port, WDT, INT) are guaranteed operational. Full peripheral functionality-including CAN, UART, and A/D-requires the higher voltage range.
Does the UPD70F3611M2GBA-GAH-AX include an integrated CAN controller, and what version does it support?
Yes, the UPD70F3611M2GBA-GAH-AX integrates a CAN 2.0B-compliant controller with 32 message objects, bit-rate programmability up to 1 Mbps, and automatic bus-off recovery. It supports both standard (11-bit) and extended (29-bit) identifier formats, enabling seamless integration into industrial fieldbus networks without external transceivers beyond physical layer components.
What are the voltage supply requirements for analog functionality on the UPD70F3611M2GBA-GAH-AX?
The UPD70F3611M2GBA-GAH-AX requires AVREF0 = 3.3–5.5 V for analog operation. However, accurate 10-bit A/D conversion mandates AVREF0 ≥ 4.0 V; below this threshold, the ADA0CE bit must be cleared to disable the A/D converter. AVREF0 is supplied independently from EVDD to minimize digital switching noise coupling into analog measurements.
How does the Power-On Clear (POC) circuit function in the UPD70F3611M2GBA-GAH-AX?
The UPD70F3611M2GBA-GAH-AX POC circuit monitors VRO (regulated output) and holds the internal reset signal asserted until VRO stabilizes within specification (2.5 V ±5%). This eliminates dependency on external reset ICs and ensures deterministic initialization even with slow or noisy VDD ramps, a critical feature for industrial equipment subjected to variable power quality.
Is the UPD70F3611M2GBA-GAH-AX pin-compatible with other members of the V850ES/FF3 family?
Yes, the UPD70F3611M2GBA-GAH-AX shares the same 80-pin FF3 package and pinout with other V850ES/FF3 devices such as µPD70F3372 and µPD70F3373. Pin Group assignments (e.g., Group 1D for P00–P03, Group 4 for P70–P711) are consistent across the FF3 series, enabling hardware reuse across variants differing primarily in Flash size and peripheral enablement.
