FAQ

What is the maximum operating frequency of the UPD70F3482AGMA-GAR-G?

The UPD70F3482AGMA-GAR-G operates at a maximum CPU clock frequency of 64 MHz, achieved using an on-chip PLL with external crystal oscillator input (typically 4–20 MHz). This frequency is fully supported across the full –40°C to +125°C temperature range and meets AEC-Q100 Grade 2 timing specifications without derating.

Does the UPD70F3482AGMA-GAR-G include built-in CAN transceiver functionality?

No, the UPD70F3482AGMA-GAR-G integrates a CAN 2.0B protocol controller only - it requires an external CAN physical-layer transceiver (e.g., TJA1042 or SN65HVD230) for bus connection. The MCU provides dedicated CAN_TX and CAN_RX pins with slew-rate control and fault detection logic compatible with industry-standard transceivers.

Is the UPD70F3482AGMA-GAR-G qualified for automotive applications?

Yes, the UPD70F3482AGMA-GAR-G is AEC-Q100 qualified to Grade 2 (–40°C to +125°C), with full test reports covering HTOL, temperature cycling, ESD, and latch-up. It is designated for automotive body electronics applications and supports functional safety development per ISO 26262 ASIL-B requirements through dual watchdogs, Flash ECC, and memory protection units.

What debug interfaces does the UPD70F3482AGMA-GAR-G support?

The UPD70F3482AGMA-GAR-G supports IEEE 1149.1 JTAG for on-chip debugging, compatible with Renesas E1 and E20 emulators. It enables full-speed real-time tracing, hardware breakpoints, register inspection, and Flash programming without halting CPU execution - critical for validating timing-critical automotive firmware.

How much user-accessible Flash and RAM does the UPD70F3482AGMA-GAR-G provide?

The UPD70F3482AGMA-GAR-G provides 512 KB of on-chip Flash memory (with 1 KB reserved for bootloader and security keys) and 48 KB of SRAM. All Flash and RAM are accessible via the V850E/SK3-H memory map, with configurable wait states and parity/ECC enabled by default for safety-critical operation.
