FAQ
What is the maximum operating frequency of the M30290FATHP#U3A?
The M30290FATHP#U3A supports a maximum CPU clock frequency of 20 MHz when using the main crystal oscillator (XT1) or PLL-derived clock. This frequency is guaranteed across the full operating temperature range (−40°C to +85°C) and supply voltage (4.5 V to 5.5 V). The M30290FATHP#U3A achieves this speed with zero wait-state execution for on-chip flash access, enabling consistent instruction throughput for time-critical control loops.
Does the M30290FATHP#U3A support in-system programming (ISP)?
Yes, the M30290FATHP#U3A supports in-system programming via its on-chip serial interface using the Renesas Flash Development Toolkit (FDT). The 256 KB flash memory can be reprogrammed while soldered on the target board, with sector erase granularity (64 KB, 8 KB, or 1 KB blocks) and security lock bits to prevent unauthorized access. The M30290FATHP#U3A does not require external high-voltage programming signals - all ISP operations use standard 5 V supply and UART or dedicated programming pins.
What is the brown-out detection (BOD) threshold for the M30290FATHP#U3A?
The M30290FATHP#U3A features a fixed brown-out detection circuit with a nominal threshold of 4.2 V ±0.2 V. When VCC drops below this level, the device asserts a hardware reset to prevent undefined operation or flash corruption. The BOD circuit remains active in all power modes (Normal, Wait, Stop) and does not require software enable. This threshold ensures reliable reset behavior for the M30290FATHP#U3A in 5 V systems subject to line sag or transient dips.
How many I/O pins does the M30290FATHP#U3A have, and what is their drive capability?
The M30290FATHP#U3A provides 85 programmable I/O pins across Ports P0–P11 (excluding power, reset, and oscillator pins). Each pin supports CMOS-level input thresholds and delivers ±10 mA sink/source current at VCC = 5 V, with voltage-tolerant inputs up to 5.5 V. The M30290FATHP#U3A also supports individual direction control, pull-up resistors (20–100 kΩ), and noise filter configuration per port, enabling direct connection to switches, LEDs, and logic-level peripherals without external buffering.
Is the M30290FATHP#U3A pin-compatible with other devices in the M16C/29 Group?
Yes, the M30290FATHP#U3A shares identical pin assignment and electrical characteristics with other 100-pin LQFP variants in the M16C/29 Group, including M30290FATHP#U5A and M30290FATHP#U7A. Differences among these variants relate solely to flash size (256 KB vs. 128 KB vs. 64 KB) and RAM allocation, not pinout or peripheral mapping. This allows hardware design reuse and firmware scalability within the same PCB layout when selecting the M30290FATHP#U3A.
