Overview

The RX140 microcontrollers in the RX100 series combine the highest processing performance and low supply current. This makes them suitable for a wide range of applications such as home appliances, industrial applications and building automation. The RX140 with an RXv2 core achieves a 48MHz maximum operating frequency, with about twice the performance of the previous RX130 operating at 32MHz. In addition, power consumption is reduced by more than 30% compared to the RX130 with 56μA/MHz during CPU operation and 0.25μA in standby mode. A new low power mode (snooze mode) also enables an additional low power consumption mode for applications that require intermittent operation. In addition, the latest capacitive touch sensor is equipped with third-generation touch IP that dramatically improves noise immunity and increases water resistance, so it can be used in a wider range of applications than ever before, including environments where noise or wet surroundings would affect accuracy. Peripheral functions have also been expanded, including CAN functionality that enables real-time communication, an AES encryption accelerator to reduce security threats such as data eavesdropping and tampering, and a true random number generator.

    Resonator Information

    Please search for your resonator on its manufacturer's site linked below. If you require optimal oscillation circuit constants for your particular system, please ask the manufacturer of the oscillator.

    For main clock resonator/subclock resonator:
    NIHON DEMPA KOGYO: Please see IC Matching Information in the RX140 column.
    KYOCERA: Click here for RX140 oscillation evaluation result.
    Murata Manufacturing: Please enter "RX140" or "R5F5140" into the IC Part Number search box. For main clock resonator / sub clock resonator.
    Seiko Instruments: Please see the matching data in the RX140 column.

    For information on resonators, please also refer to the following application note.
