FAQ
What is the operating temperature range for R5F2LA67ANFP#30?
The R5F2LA67ANFP#30 is rated for −20°C to +85°C (N version). This industrial-grade temperature range ensures reliable operation in appliance control panels, thermostats, and indoor industrial sensors where ambient conditions remain within standard commercial environments. The device does not support extended −40°C operation - for that, the D-version part (R5F2LA67ADFP) must be selected.
Does R5F2LA67ANFP#30 support in-circuit debugging?
Yes, R5F2LA67ANFP#30 includes full on-chip debug functionality compatible with Renesas E1 and E20 emulators via the single-wire debug interface. This enables real-time breakpoints, register inspection, flash programming, and trace without requiring external JTAG headers - simplifying development and reducing debug footprint on target PCBs.
How many A/D converter channels does R5F2LA67ANFP#30 have, and what is their resolution?
R5F2LA67ANFP#30 integrates a 10-bit successive-approximation A/D converter with 8 input channels, sample-and-hold circuitry, and sweep mode for automatic channel sequencing. It also includes an on-die temperature sensor calibrated for −20°C to +85°C, usable for system thermal monitoring without external components.
What LCD display configurations does R5F2LA67ANFP#30 support?
R5F2LA67ANFP#30 supports static, 1/2, 1/3, and 1/4 duty drive with up to 4 common outputs and 32 segment outputs. Its LCD control circuit accepts bias voltages of 1/2 or 1/3 and supports multiplexed character displays - commonly used in 4-digit 7-segment or 2-line alphanumeric panels found in appliances and thermostats.
Is R5F2LA67ANFP#30 pin-compatible with other R8C/LA6A Group MCUs?
Yes, all R8C/LA6A Group devices in the 64-pin LQFP package (PLQP0064KB-A/PLQP0064GA-A), including R5F2LA64ANFP, R5F2LA66ANFP, R5F2LA67ANFP#30, and R5F2LA68ANFP, share identical pinouts and peripheral mappings. Firmware and hardware designs can be scaled across this family by changing only flash/RAM capacity - enabling platform reuse and simplified qualification.
