FAQ

What is the maximum operating frequency and corresponding supply voltage for M30620FCAFP#D3?

The M30620FCAFP#D3 achieves a shortest instruction execution time of 62.5 ns at 16 MHz XIN frequency with VCC = 5 V and no software wait states. It supports 4.2–5.5 V operation under these conditions. At 10 MHz with software one-wait, it operates down to 2.7 V, enabling flexible power rail design in mixed-voltage systems. This specification is confirmed in the M16C/62A Group datasheet section "Electrical Characteristics" and applies specifically to the flash memory 5 V version denoted by the 'F' in M30620FCAFP#D3.

Does M30620FCAFP#D3 include a hardware multiplier and how is it used in practice?

Yes, the M30620FCAFP#D3 integrates a dedicated hardware multiplier unit within its M16C/60 Series CPU core. This enables single-cycle 16×16-bit multiplication, accelerating mathematical operations critical for digital filtering, motor control algorithms, and sensor linearization. The multiplier is accessed via specific CPU instructions and does not require software emulation - reducing code size and improving deterministic timing in real-time loops. Its presence is documented in the "Central Processing Unit (CPU)" chapter of the M16C/62A Group description document.

How many analog input channels does M30620FCAFP#D3 support and what is their resolution?

The M30620FCAFP#D3 supports 10-bit resolution A-D conversion across 8 dedicated analog input channels (AN0–AN7, pins P100–P107), with provision to expand to 10 channels using ANEX0/ANEX1 (P95/P96). All channels share a common 10-bit successive approximation register (SAR) structure and reference voltage (VREF). This configuration is explicitly defined in Table 1.1.1 ("Performance outline") and the "A-D Converter" section of the M16C/62A Group documentation.

What packaging and pin-count options exist for M30620FCAFP#D3?

The M30620FCAFP#D3 is exclusively offered in the 100-pin plastic molded QFP package designated as 100P6S-A (FP suffix), measuring 14 mm × 20 mm with 0.65 mm lead pitch. The alternate GP suffix (e.g., M30620FCAGP) denotes the 100P6Q-A variant, which is mechanically identical but qualified for different thermal and reliability standards. No other package types - such as LQFP, TQFP, or BGA - are specified for this flash memory variant in Renesas' official product lineup.

Can M30620FCAFP#D3 operate in both single-chip and memory expansion modes, and how is the mode selected?

Yes, the M30620FCAFP#D3 supports both single-chip mode (internal memory only) and memory expansion mode (external bus interface active). Mode selection is controlled by the BYTE pin: logic low selects 16-bit external data bus width and enables full external addressing, while logic high selects 8-bit width. The RESET pin state and internal mode registers further configure operation. This dual-mode capability is detailed in the "Pin Description" section and "Memory Expansion" subsection of the M16C/62A Group documentation, confirming hardware-supported flexibility for varying system complexity.
