Renesas Electronics Corporation Supervisors X40411V8I-BT1

The X40411V8I-BT1 is a dual voltage monitor and integrated CPU supervisor designed for applications requiring power-on reset control, watchdog timer functionality, and voltage supervision. It features the ability to monitor two voltage levels, with adjustable reset thresholds, ensuring system stability during power fluctuations. The device operates within a supply voltage range of 2.7V to 5.5V and has a low power consumption profile, with typical standby currents of 25µA (watchdog on) and 6µA (watchdog off). The X40411V8I-BT1 includes a fault detection register and supports a selectable power-on reset timeout of 0.05s, 0.2s, 0.4s, or 0.8s. It also offers a watchdog timer with selectable intervals of 25ms, 200ms, or 1.4s, providing an additional layer of protection for microcontroller operations. The device incorporates 4Kbits of EEPROM with a 16-byte page write mode and a typical write cycle time of 5ms, along with built-in inadvertent write protection. This supervisor is suitable for various applications, including communication equipment, industrial systems, and computer systems, making it a versatile choice for engineers looking to enhance system reliability and performance.
