FAQ
What is the maximum operating frequency and supply voltage range for the R5F2L38AMDFA#V0?
The R5F2L38AMDFA#V0 operates at up to 20 MHz when supplied with 2.7–5.5 V, and supports 5 MHz operation down to 1.8 V. Its voltage detection circuit provides programmable reset thresholds, and the device maintains full functionality across its rated -40°C to +85°C industrial temperature range.
Does the R5F2L38AMDFA#V0 support background data flash programming during application execution?
Yes, the R5F2L38AMDFA#V0 supports Background Operation (BGO) for data flash, allowing erase and write operations to proceed concurrently with CPU code execution. This enables seamless firmware updates and parameter storage without interrupting real-time control tasks.
How many LCD segments and commons does the R5F2L38AMDFA#V0 support, and what bias/duty options are available?
The R5F2L38AMDFA#V0 supports up to 56 segment outputs and 8 common outputs. It provides selectable LCD bias (1/2, 1/3, 1/4) and duty (static, 1/2, 1/3, 1/4, 1/8) configurations, with integrated voltage multiplier and dedicated regulator enabling direct drive of multiplexed LCDs without external components.
Which timers in the R5F2L38AMDFA#V0 support complementary PWM generation for motor control?
Timer RD (16-bit ×2) in the R5F2L38AMDFA#V0 supports complementary PWM mode for three-phase waveform output on six pins, with triangular wave modulation and programmable dead-time insertion-making it suitable for brushless DC motor control in appliances like washing machines.
Is the R5F2L38AMDFA#V0 pin-compatible with other devices in the R8C/L3xM family?
No, the R5F2L38AMDFA#V0 uses an 80-pin LQFP (PLQP0080JA-A) package and is not pin-compatible with 52-pin, 64-pin, or 100-pin variants in the R8C/L3xM family. Pin assignments differ significantly across groups due to varying I/O counts, LCD resources, and peripheral mappings-even within the same package type (e.g., FA vs FP).
