FAQ

What is the maximum operating frequency of the UPD78F0562MC-CAA-AX?

The UPD78F0562MC-CAA-AX supports a maximum system clock frequency of 20 MHz. This can be achieved using either the internal high-speed oscillator (HSO) or an external crystal/resonator connected to the X1/X2 pins. The HSO requires no external components and is factory-trimmed to ±2% accuracy across temperature and voltage, enabling rapid prototyping and simplified BOMs.

Does the UPD78F0562MC-CAA-AX support in-system programming?

Yes, the UPD78F0562MC-CAA-AX supports in-system programming (ISP) via its on-chip Flash memory. Firmware updates can be performed through the UART interface using Renesas' Flash development toolkit (FDK) or custom bootloader code. The Flash is rated for 100,000 write/erase cycles and retains data for 10 years at 85°C, making it suitable for field-upgradable industrial equipment.

What are the power supply requirements for the UPD78F0562MC-CAA-AX?

The UPD78F0562MC-CAA-AX requires a single 4.0 V to 5.5 V supply on VDD pins, with dedicated AVREF and AVSS pins for analog subsystems. It features an internal voltage regulator for the core and separate I/O power domains. The device includes a programmable voltage monitor that triggers reset at either 4.2 V or 3.8 V, ensuring reliable operation under brown-out conditions without external supervision circuits.

How many I/O ports does the UPD78F0562MC-CAA-AX have, and what are their capabilities?

The UPD78F0562MC-CAA-AX provides eight I/O ports (P0–P7 and P12), totaling 56 programmable pins in the 64-pin LQFP package. All ports support quasi-bidirectional operation with weak pull-ups, and most pins offer alternate functions including UART, I²C, timer I/O, and ADC inputs. Port 0 doubles as an 8-bit external data bus, enabling expansion with parallel peripherals or memory.

Is the UPD78F0562MC-CAA-AX RoHS-compliant and lead-free?

Yes, the UPD78F0562MC-CAA-AX is RoHS-compliant and lead-free, meeting EU Directive 2011/65/EU and subsequent amendments. The "-AX" suffix in the part number denotes lead-free packaging per Renesas' standard product marking convention. The device uses halogen-free molding compound and complies with JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) for surface-mount assembly.
