For engineers reviewing the UPD70F3382M2GJA-GAE-AX datasheet, UPD70F3382M2GJA-GAE-AX pinout, UPD70F3382M2GJA-GAE-AX application, or UPD70F3382M2GJA-GAE-AX equivalent, key selection considerations include its 144-pin LQFP package, EVDD/BVDD dual-supply architecture, CAN timing compliance per ISO 11898-1, A/D conversion accuracy at AVREF0 ≥ 4.0 V, and Flash programming support in standard operating mode.

Technical Context

The UPD70F3382M2GJA-GAE-AX implements the V850ES CPU core with Harvard architecture, supporting 32-bit fixed-point arithmetic and 16-bit instruction encoding. Its clock system includes main crystal oscillator (4–16 MHz), sub-oscillator (32–35 kHz), internal RC (240 kHz), and PLL with programmable multiplication factor for system clock synthesis up to 32 MHz.

Peripheral integration includes three UARTs, two I²C interfaces, four CSI synchronous serial ports, 16-bit timer arrays (TMR0–TMR3), watchdog timer (WDT), and programmable I/O ports grouped by voltage domain (EVDD, BVDD, AVREF0). The device uses SuperFlash® technology licensed from Silicon Storage Technology for Flash endurance and data retention.

The V850ES/FE3 product line was designed for high-reliability industrial and automotive body electronics applications requiring integrated CAN, robust Flash memory, and deterministic real-time performance in extended temperature ranges.

FAQ

What is the maximum operating frequency of the UPD70F3382M2GJA-GAE-AX?

The UPD70F3382M2GJA-GAE-AX supports a maximum system clock frequency of 32 MHz when using the PLL with a 4–16 MHz crystal input. Peripheral clock frequencies are limited to 20 MHz when VDD is below 4.0 V, and full AC characteristics apply only within specified voltage and temperature ranges per the A-grade electrical specifications.

Does the UPD70F3382M2GJA-GAE-AX include an integrated CAN transceiver?

No, the UPD70F3382M2GJA-GAE-AX contains a CAN 2.0B protocol controller but requires an external CAN physical-layer transceiver (e.g., TJA1040 or SN65HVD230) for bus connection. Its CTX0/CRX0 pins provide differential logic-level signals compliant with ISO 11898-1, not bus-voltage signaling.

What is the Flash memory endurance specification for the UPD70F3382M2GJA-GAE-AX?

The UPD70F3382M2GJA-GAE-AX uses SuperFlash® technology licensed from Silicon Storage Technology, providing guaranteed 100,000 program/erase cycles and 20-year data retention at 85°C. Flash programming is supported in normal operating mode with VDD ≥ 3.3 V and AVREF0 ≥ 3.3 V.

How does the POC (Power-On Clear) function operate in the UPD70F3382M2GJA-GAE-AX?

The UPD70F3382M2GJA-GAE-AX integrates a POC circuit that automatically asserts internal reset until the regulated output voltage VRO stabilizes (tREG ≤ 1 ms). This eliminates the need for an external reset supervisor IC and ensures deterministic initialization even during slow power ramp-up or brown-out conditions.

Is the UPD70F3382M2GJA-GAE-AX qualified for automotive applications?

The UPD70F3382M2GJA-GAE-AX is classified as NEC's "Standard" quality grade, intended for industrial, office, and communications equipment-not automotive safety-critical systems. While it supports CAN and operates from -40°C to +85°C, it lacks AEC-Q100 qualification and functional safety features required for automotive powertrain or ADAS applications.
