Description:RL78/G14 microcontrollers balance the industry's lowest level of consumption current (CPU: 66 μA/MHz, standby (STOP): 240 nA) and a high calculation performance of51.2 DMIPS (32 MHz). The built-in high-function timer supports three-phase motor control using three-phase complementary PWM output. They have an on-chip oscillator, data flash, A/D and D/A converters, comparator, and more. Built-in safety features (function that detects illegal operation of hardware) enable support for the household appliance saf
The recommended power-on sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization of the internal voltage regulators and prevents latch-up.
It is recommended to tri-state the JTAG pins during power-down or reset to prevent unwanted data corruption or bus contention. This can be done by setting the JTAG pins as inputs or using an external buffer to isolate the JTAG interface.
The maximum allowed clock skew is typically specified as 1-2 clock cycles, depending on the specific peripheral and system requirements. Excessive clock skew can cause data corruption or synchronization issues.
To optimize flash memory programming time, use the fastest available clock frequency, enable the flash accelerator (if available), and use a programming algorithm that minimizes the number of erase and write cycles. Additionally, consider using a flash memory controller with a high-speed interface, such as QSPI or HyperBus.
The R5F104BDAFP#30 has a maximum junction temperature (TJ) of 150°C. To ensure reliable operation, it is essential to provide adequate heat dissipation, such as using a heat sink or thermal pad, and to avoid exposing the device to high ambient temperatures or thermal gradients.
