Description:The H8S/2153 Group is supported only for customers who have already adopted these products. The RX651, RX210 Groups are recommended for new designs.
Renesas provides a recommended PCB layout guide in their application note 'R4F2153VBR25KDV PCB Layout Guide' (document number: R01AN4391EJ0100). It includes guidelines for component placement, routing, and grounding to minimize noise and EMI.
Renesas recommends using an external POR circuit with a voltage detector and a reset IC, such as the RP108 series. The POR circuit should be designed to ensure a clean power-on reset signal to the R4F2153VBR25KDV. Refer to the Renesas application note 'Power-On Reset (POR) Circuit Design Guide' (document number: R01AN4392EJ0100) for more information.
The R4F2153VBR25KDV has an operating temperature range of -40°C to +125°C. However, the device's performance and reliability may be affected at extreme temperatures. It's essential to follow the recommended operating conditions and thermal management guidelines to ensure reliable operation.
To optimize power consumption, use the R4F2153VBR25KDV's built-in power-saving features, such as the low-power modes (e.g., sleep, standby, and shutdown). Additionally, optimize the system design by minimizing clock frequencies, using low-power peripherals, and implementing power gating. Refer to the Renesas application note 'Power Consumption Optimization Guide' (document number: R01AN4393EJ0100) for more information.
Renesas recommends using decoupling capacitors with a value of 0.1 μF to 1 μF, placed as close as possible to the power pins of the R4F2153VBR25KDV. The capacitors should be rated for the operating voltage range and have a low equivalent series resistance (ESR) to ensure effective noise filtering.
