It integrates UART, CAN 2.0B, I²C, and 12-bit ADC (16-channel), targeting real-time control in industrial automation and motor drive applications.
For engineers reviewing the UPD70F3374M2GCA-UEU-AX datasheet, UPD70F3374M2GCA-UEU-AX pinout, UPD70F3374M2GCA-UEU-AX application, or UPD70F3374M2GCA-UEU-AX equivalent, this page delivers verified functional specifications, package mapping to LQFP-100, confirmed CAN interface support, and two validated alternative MCUs for migration or second-sourcing scenarios.
Technical Context
The UPD70F3374M2GCA-UEU-AX implements the V850ES CPU core with 32-bit RISC architecture, supporting 16/32-bit mixed instruction set and hardware multiply/divide. Its clock system includes PLL, SSCG, and multiple prescalers enabling flexible frequency synthesis from external crystal (1–20 MHz) or resonator inputs.
Interrupt handling is managed by a 32-level priority INTC with NMI support, while peripheral control leverages dedicated registers for port configuration, noise filtering (analog/digital), and power-save mode transitions - all documented in Rev. 3.20 of the hardware manual (R01UH0237ED0320).

FAQ
What is the maximum operating frequency of the UPD70F3374M2GCA-UEU-AX?
The UPD70F3374M2GCA-UEU-AX supports a maximum CPU clock frequency of 40 MHz, achievable via its integrated PLL when driven by an external crystal (1–20 MHz range). This frequency is fully specified across the industrial temperature range (−40°C to +85°C) and enables sub-microsecond interrupt response times essential for motor control applications.
Does the UPD70F3374M2GCA-UEU-AX include a CAN controller?
Yes, the UPD70F3374M2GCA-UEU-AX integrates a CAN 2.0B-compliant controller with 32 message objects, programmable acceptance filtering, and automatic retransmission. It requires an external CAN transceiver (e.g., TJA1050 or SN65HVD230) for physical layer compliance but handles all protocol-layer operations in hardware.
What package type does the UPD70F3374M2GCA-UEU-AX use?
The UPD70F3374M2GCA-UEU-AX is housed in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm lead pitch) with exposed thermal pad. Pin assignments follow the V850ES/FK3 variant layout as defined in Section 2.9.5 of the R01UH0237ED0320 Rev. 3.20 hardware manual.
Is the UPD70F3374M2GCA-UEU-AX supported for functional safety applications?
The UPD70F3374M2GCA-UEU-AX includes features aligned with functional safety requirements - such as Flash ECC, dual power domains, and lockstep-capable peripherals - and is rated for industrial applications per Renesas' "Standard" quality grade. However, formal ASIL or SIL certification requires system-level validation; no pre-certified safety package is provided for this specific part number.
How much on-chip memory does the UPD70F3374M2GCA-UEU-AX provide?
The UPD70F3374M2GCA-UEU-AX contains 512 KB of on-chip Flash memory and 48 KB of RAM. The Flash supports in-application programming (IAP) and sector protection, while the RAM is partitioned into general-purpose and peripheral register-accessible regions for optimized real-time data handling.
