FAQ

What is the operating temperature range of the R5F364A6NFA#U0?

The R5F364A6NFA#U0 is rated for operation from -20°C to +85°C. This commercial-grade temperature specification is defined in Table 1.3 of the R01DS0032EJ0200 datasheet and applies specifically to the FA package variant (PRQP0100JD-B). The device uses on-chip voltage detection and thermal monitoring circuits to maintain reliable operation across this range without external compensation.

Does the R5F364A6NFA#U0 support HDMI-CEC functionality?

Yes, the R5F364A6NFA#U0 includes a dedicated CEC transceiver function accessible via pin P8_5 (NMI/SD/CEC). As documented in Table 1.2 and Section 1.6, it supports CEC transmit/receive, arbitration loss detection, and automatic ACK output at 32 kHz - fully compliant with HDMI CEC v1.4 specifications for system control interoperability.

How many analog-to-digital converter channels does the R5F364A6NFA#U0 provide?

The R5F364A6NFA#U0 integrates a 10-bit A/D converter with 26 input channels: AN0–AN7 (8 channels), AN0_0–AN0_7 (8 channels), AN2_0–AN2_7 (8 channels), plus ANEX0 and ANEX1 (2 extended inputs). Conversion time is specified at 1.72 µs, and the reference voltage is configurable via the VREF pin, as confirmed in Table 1.2 and Figure 1.3 block diagram.

What package type is used for the R5F364A6NFA#U0?

The R5F364A6NFA#U0 is supplied in a 100-pin plastic quad flat package designated PRQP0100JD-B (previous code: 100P6F-A). This package has 0.65 mm lead pitch, 20 mm × 14 mm body size, and complies with JEDEC MS-026AC. Pin assignments match Figure 1.4 and Table 1.4 in the R01DS0032EJ0200 datasheet.

Can the R5F364A6NFA#U0 operate with different supply voltages for core and I/O?

Yes, the R5F364A6NFA#U0 employs dual power domains: VCC1 (2.7–5.5 V) supplies the CPU core, analog peripherals, and internal RAM; VCC2 (2.7 V to VCC1) powers the external bus interface and associated I/O pins. This separation allows mixed-voltage operation - for example, 3.3 V core with 5 V external memory or peripheral interfaces - as detailed in Table 1.6 and Section 1.6.
