For engineers reviewing the UPD70F3370M2GBA-GAH-AX datasheet, UPD70F3370M2GBA-GAH-AX pinout, UPD70F3370M2GBA-GAH-AX application, or UPD70F3370M2GBA-GAH-AX equivalent, key selection considerations include its A-grade industrial temperature range (−40°C to +85°C), EVDD-supplied I/O groups, dual voltage regulator outputs (VRO = 2.5 V), and support for external crystal (4–16 MHz) with PLL multiplication.
Technical Context
The UPD70F3370M2GBA-GAH-AX implements the V850ES CPU core with Harvard architecture, supporting 32-bit fixed-point arithmetic and 16-bit compressed instruction set. Its clock system includes main and sub oscillators, internal RC oscillator (240 kHz), PLL with programmable multiplication factor, and Spread Spectrum Clock Generator (SSCG) for EMI reduction.
It integrates peripheral functions including UART, CSI, I²C, 16-bit timer arrays (TMR, RTMR), watchdog (WDT), power-on reset (POR), low-voltage interrupt (LVI), and programmable I/O ports grouped by supply domain (EVDD, BVDD, AVREF0). The device uses licensed SuperFlash® technology for Flash endurance and data retention.

FAQ
What is the maximum operating frequency of the UPD70F3370M2GBA-GAH-AX?
The UPD70F3370M2GBA-GAH-AX supports a maximum CPU clock frequency of 32 MHz when VDD is between 4.0 V and 5.5 V. At lower supply voltages (3.3–3.5 V), only core functions like CPU, Flash, RAM, and basic I/O remain operational - peripheral clocks are restricted or disabled per the datasheet's operating condition table.
Does the UPD70F3370M2GBA-GAH-AX include an integrated CAN controller?
Yes, the UPD70F3370M2GBA-GAH-AX integrates a full CAN 2.0B controller with 32 message objects, programmable bit timing, and automatic error confinement. It uses dedicated pins PCM0 (TX) and PCM1 (RX) and does not require external CAN protocol logic - only a physical-layer transceiver is needed for bus connection.
What package type and pin count does the UPD70F3370M2GBA-GAH-AX use?
The UPD70F3370M2GBA-GAH-AX is packaged in an 80-pin plastic QFP (Quad Flat Package) with 0.65 mm lead pitch, designated as FF3 in NEC's package nomenclature. This matches the pinout and thermal profile defined in datasheet section 5.1 and supports standard surface-mount assembly processes.
Is the UPD70F3370M2GBA-GAH-AX qualified for automotive applications?
The UPD70F3370M2GBA-GAH-AX is specified for A-grade industrial operation (−40°C to +85°C) and classified as "Standard" quality per NEC's documentation. While used historically in non-safety-critical automotive body control modules, it is not certified to AEC-Q100 or designated for safety-related vehicle systems.
What voltage references does the UPD70F3370M2GBA-GAH-AX support for its A/D converter?
The UPD70F3370M2GBA-GAH-AX A/D converter uses AVREF0 as its analog reference input, which must be supplied externally in the range of 3.3 V to 5.5 V. The device specifies that ADC operation is not guaranteed below 4.0 V on AVREF0 (ADA0CE bit must be cleared), and all 16 analog input channels (P70–P711) are tied to this domain.
