FAQ

What is the maximum operating frequency of the UPD70F3370AM1GBA-GAH-AX?

The UPD70F3370AM1GBA-GAH-AX supports a maximum system clock frequency of 32 MHz when operated at 4.0–5.5 V supply voltage. At 3.3–4.0 V, the maximum peripheral clock frequency is limited to 20 MHz per the electrical specifications in section 2.3 of the U18565EE1V2DS00 datasheet. The UPD70F3370AM1GBA-GAH-AX achieves this via its integrated PLL clock generator with programmable multiplication ratio.

Does the UPD70F3370AM1GBA-GAH-AX include an integrated CAN transceiver?

No, the UPD70F3370AM1GBA-GAH-AX integrates only the CAN protocol controller (CAN 2.0B compliant), not the physical layer transceiver. Pins P40 (CAN_TX) and P91 (CAN_RX) require connection to an external CAN transceiver such as the NXP TJA1040 or Infineon TLE6250 to interface with the CAN bus. This separation allows design flexibility in voltage level, fault protection, and ESD robustness.

What is the A/D converter resolution and channel count on the UPD70F3370AM1GBA-GAH-AX?

The UPD70F3370AM1GBA-GAH-AX features a 10-bit successive-approximation A/D converter with 16 analog input channels (AN0–AN15), mapped to pins P70–P711. Conversion time is 1.2 μs (typical) at 32 MHz system clock, and the reference voltage is selectable between AVREF0 and internal bandgap. The UPD70F3370AM1GBA-GAH-AX supports hardware-triggered sampling synchronized to timer or external events.

Is the UPD70F3370AM1GBA-GAH-AX RoHS-compliant?

Yes, the UPD70F3370AM1GBA-GAH-AX is a lead-free (RoHS-compliant) device. Section 5.2.2 of the U18565EE1V2DS00 datasheet explicitly states that "Lead-Free Products are identified by marking 'LF' on the top surface of the package." The suffix '-GAH' in UPD70F3370AM1GBA-GAH-AX denotes lead-free packaging per NEC's product marking convention.

What debug interface does the UPD70F3370AM1GBA-GAH-AX support?

The UPD70F3370AM1GBA-GAH-AX supports on-chip debugging via the JTAG interface using the standard IEEE 1149.1 boundary-scan architecture. Debug functionality includes halt-mode debugging, breakpoint setting, register and memory access, and flash programming. The JTAG pins (TCK, TMS, TDI, TDO, TRST) are multiplexed with port pins P50–P54 and require proper configuration during reset to enable debug mode.
