Product details
Overview
UPD70F3617M1GKA-GAK-AX from NEC Electronics is a 32-bit V850ES/FF3-L single-chip microcontroller with 256 KB Flash, 16 KB RAM, and integrated CAN 2.0B controller. It operates at up to 20 MHz via PLL (input 4–16 MHz crystal), supports -40°C to +125°C (A2-grade), and targets automotive body control modules requiring real-time I/O, analog sensing, and robust communication.
For engineers reviewing the UPD70F3617M1GKA-GAK-AX datasheet, UPD70F3617M1GKA-GAK-AX pinout, UPD70F3617M1GKA-GAK-AX application, or UPD70F3617M1GKA-GAK-AX equivalent, this page delivers verified electrical specs, package mapping, functional pin roles, automotive-grade thermal performance, and validated alternative MCUs for ECU redesign and supply continuity planning.
Technical Context
The UPD70F3617M1GKA-GAK-AX implements the V850ES CPU core with Harvard architecture, supporting 32-bit integer operations and 16-bit compressed instructions. Its clock system integrates a main crystal oscillator (4–16 MHz), sub-oscillator (32.768 kHz), 240 kHz/8 MHz internal RC oscillators, and a PLL with 10–20 MHz output and ≤2 ns peak-to-peak jitter.
It features dual voltage domains: EVDD/EVSS for digital I/O and logic (3.3–5.5 V), and AVREF0/AVSS for 10-bit ADC (up to 16 channels, 1 µs conversion). Power management includes six low-power modes (IDLE1/2, SUB, SubIDLE, STOP, HALT) with current as low as 20 µA in SubIDLE mode using crystal.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Renesas RL78/F13 | 16-bit core, 128 KB Flash, 10-bit ADC, CAN 2.0B; lower max frequency (24 MHz CPU, but 12 MHz effective due to 2-cycle execution) | Targeted at cost-sensitive body electronics; lacks A2-grade extended temperature support | Select when BOM cost is primary constraint and -40°C to +105°C suffices; requires software adaptation for V850ES instruction set differences |
| Infineon XC2000 family (e.g., XC2267) | 32-bit C166-derived core, 512 KB Flash, 64 KB RAM, dual CAN, higher integration (on-chip voltage regulators, LIN) | Designed for high-complexity powertrain and chassis control; larger footprint (100-pin TQFP) | Select for next-generation ECU platforms needing higher memory, dual CAN, and enhanced safety features (ASIL-B ready); requires PCB redesign |
Compared with RL78/F13 and XC2267, the UPD70F3617M1GKA-GAK-AX delivers optimal balance of A2-grade thermal resilience, integrated POC regulation, and proven V850ES toolchain support-making it ideal for legacy and mid-life automotive ECUs where reliability and supply continuity outweigh raw compute density.

FAQ
What is the maximum operating frequency of the UPD70F3617M1GKA-GAK-AX?
The UPD70F3617M1GKA-GAK-AX achieves a maximum system clock frequency of 20 MHz using its on-chip PLL with a 4–16 MHz crystal input. Without PLL, the maximum is 16 MHz. This frequency drives both CPU execution and peripheral timing-including CAN bit rate generation and ADC sampling-ensuring deterministic real-time response in automotive control loops.
Does the UPD70F3617M1GKA-GAK-AX support CAN communication?
Yes, the UPD70F3617M1GKA-GAK-AX integrates a full CAN 2.0B controller with 32 message objects, programmable bit timing, and automatic bus-off recovery. It supports data rates up to 1 Mbit/s when running at 20 MHz and requires only an external CAN transceiver (e.g., TJA1042) for physical layer compliance.
What temperature grade does the UPD70F3617M1GKA-GAK-AX carry?
The UPD70F3617M1GKA-GAK-AX is rated for the A2-grade temperature range: -40°C to +125°C ambient. This qualification meets automotive under-hood requirements and is validated per NEC's "Specific" quality assurance program for safety-critical systems-not standard commercial-grade operation.
How much Flash and RAM does the UPD70F3617M1GKA-GAK-AX include?
The UPD70F3617M1GKA-GAK-AX contains 256 KB of on-chip SuperFlash® memory and 16 KB of SRAM. The Flash supports in-system programming with 100,000 erase/write cycles and sector protection; the RAM includes a retention flag enabling low-power data preservation during STOP mode.
What power supply domains does the UPD70F3617M1GKA-GAK-AX use?
The UPD70F3617M1GKA-GAK-AX employs three independent supply domains: EVDD/EVSS for digital I/O and logic (3.3–5.5 V), AVREF0/AVSS for analog peripherals including the 10-bit ADC, and VRO (2.5 V regulated output) for internal reference. This separation minimizes noise coupling and ensures ADC accuracy across operating conditions.
