The internal temperature sensor also operates across this full range.
Does R5F2LA87ADFP#30 support in-application programming of its data flash?
Yes, R5F2LA87ADFP#30 supports full in-application programming (IAP) of both program flash and its two 1 KB data flash blocks. The on-chip flash rewrite function allows firmware to update calibration tables, device configuration, or usage logs without halting execution-critical for field-upgradable appliances and industrial controllers where downtime must be minimized.
How many LCD segments can R5F2LA87ADFP#30 drive, and what bias/duty options are supported?
R5F2LA87ADFP#30 integrates an LCD drive control circuit supporting up to 40 segment outputs and 4 common outputs. It supports static, 1/2, 1/3, and 1/4 duty drive modes with 1/2 and 1/3 bias options-enabling direct connection to alphanumeric LCD modules used in thermostats, multimeters, and appliance displays without external driver ICs or external bias resistors.
What serial communication interfaces are available on R5F2LA87ADFP#30?
R5F2LA87ADFP#30 provides UART0, UART2, and a shared Synchronous Serial Unit (SSU)/I²C-bus interface. UART2 supports full I²C-bus mode (master/slave), enabling direct connection to temperature sensors, EEPROMs, and display controllers. Both UARTs support multiprocessor communication, making R5F2LA87ADFP#30 suitable for multi-node sensor networks and modular HMI architectures.
Is there hardware support for real-time clock functionality in R5F2LA87ADFP#30?
Yes, R5F2LA87ADFP#30 includes Timer RH configured as a real-time clock (RTC) module capable of counting seconds, minutes, hours, day of week, date, month, and year. It operates independently using the 32 kHz XCIN/XCOUT crystal oscillator, maintaining timekeeping during stop mode with only 1.3 µA consumption-ideal for timestamping events in energy meters, data loggers, and maintenance-scheduled appliances.
