For engineers reviewing the UPD70F3915GF(R)-GAS-AX datasheet, UPD70F3915GF(R)-GAS-AX pinout, UPD70F3915GF(R)-GAS-AX application, or UPD70F3915GF(R)-GAS-AX equivalent, key selection criteria include its V850E ISA compatibility, CAN interface support, Flash endurance (100K erase/write cycles), and industrial-grade temperature range (−40°C to +85°C) - all critical for long-lifecycle embedded deployments.

Technical Context

The UPD70F3915GF(R)-GAS-AX implements the V850E1 CPU core with 5-stage pipeline, supporting both little-endian and big-endian data access. Its clock system integrates a PLL with selectable input sources (external crystal, ceramic resonator, or internal RC oscillator) and programmable division ratios to generate stable 64 MHz core clocks.

Peripheral integration includes dual 16-bit timer/event counters with PWM, capture/compare, and pulse-width measurement modes; a full-CAN 2.0B controller with 32 message objects and FIFO buffering; and up to 80 general-purpose I/O pins with configurable pull-up/down and noise filtering - enabling direct interfacing with sensors, actuators, and fieldbus transceivers without external glue logic.

FAQ

What is the maximum operating frequency of the UPD70F3915GF(R)-GAS-AX?

The UPD70F3915GF(R)-GAS-AX supports a maximum CPU clock frequency of 64 MHz, achieved via its integrated PLL when driven by an external 8 MHz crystal. This frequency is fully supported across the specified industrial temperature range (−40°C to +85°C) and supply voltage (2.7–5.5 V), enabling deterministic real-time execution for motor control and automation tasks. The UPD70F3915GF(R)-GAS-AX datasheet confirms this rating under "Electrical Specifications" (Chapter 28).

Does the UPD70F3915GF(R)-GAS-AX include a CAN controller?

Yes, the UPD70F3915GF(R)-GAS-AX integrates a full CAN 2.0B controller compliant with ISO 11898-1, supporting bit rates up to 1 Mbps and featuring 32 message objects with hardware-based acceptance filtering and FIFO buffering. This eliminates the need for external CAN protocol ICs in industrial networking applications. The UPD70F3915GF(R)-GAS-AX hardware manual (Section 5.4) details register-level configuration and interrupt handling for CAN operations.

What package type and pin count does the UPD70F3915GF(R)-GAS-AX use?

The UPD70F3915GF(R)-GAS-AX is supplied in a 100-pin LQFP package measuring 14 mm × 14 mm with 0.5 mm pitch and an exposed thermal pad. This package is mechanically and electrically compatible with other V850E/IG4-H family members such as μPD70F3919 and μPD70F3920, enabling design reuse across performance tiers. Pin assignments are documented in Section 1.5.1 of the UPD70F3915GF(R)-GAS-AX Hardware User's Manual Rev.3.00.
