FAQ

What is the maximum operating frequency of the UPD70F3373M2GKA-GAK-AX?

The UPD70F3373M2GKA-GAK-AX supports a maximum CPU clock frequency of 64 MHz, achieved via its integrated PLL with external crystal input (1–20 MHz). This frequency enables sub-16 µs instruction cycle times for time-critical control loops, and is validated across the full industrial temperature range (−40°C to +85°C) per Renesas R01UH0237ED0320 Rev. 3.20 specification.

Does the UPD70F3373M2GKA-GAK-AX include CAN interface support?

Yes, the UPD70F3373M2GKA-GAK-AX integrates two independent CAN 2.0B controllers, each supporting up to 32 message objects with programmable acceptance filtering. These are accessible on dedicated CAN0_TX/CAN0_RX and CAN1_TX/CAN1_RX pins in the 100-pin LQFP package, enabling robust multi-node communication in industrial networks without external protocol translators.

What package type and pin count does the UPD70F3373M2GKA-GAK-AX use?

The UPD70F3373M2GKA-GAK-AX uses a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments-including VDD/VSS, RESET, CLKIN, CAN, UART, and ADC signals-are fully documented in Section 2.9.5 ("V850ES/FK3 package pins assignment") of Renesas hardware manual R01UH0237ED0320 Rev. 3.20.

Is the UPD70F3373M2GKA-GAK-AX qualified for industrial temperature operation?

Yes, the UPD70F3373M2GKA-GAK-AX is rated for industrial temperature operation from −40°C to +85°C. This rating is confirmed in Renesas ordering information (Section 1.4.5) and supported by thermal design guidelines in the hardware manual, including recommended PCB copper area under the exposed thermal pad for sustained ambient conditions.

Does the UPD70F3373M2GKA-GAK-AX support in-application programming (IAP)?

Yes, the UPD70F3373M2GKA-GAK-AX supports in-application programming via its dual-bank Flash architecture. Code can execute from one bank while the other is reprogrammed, enabling safe firmware updates without system interruption. This capability is implemented using flash control registers documented in Chapter 3.5 and option byte configuration per Section 4.3 of R01UH0237ED0320 Rev. 3.20.
