The DS4510 is a CPU Supervisor chip from Maxim Integrated, which integrates 64 bytes of EEPROM memory and four programmable, non-volatile (NV) I/O pins. It is configured with an industry-standard I2C interface that supports either fast-mode (400kbps) or standard-mode (100kbps) communication. The I/O pins can be used as general-purpose I2C-to-parallel I/O expander with unlimited read/write capability. EEPROM registers allow the power-on value of the I/O pins to be adjusted to keep track of the system's state through power cycles, and the CPU supervisor's timer can be adjusted between 125ms and 1000ms to meet most any application need.
The DS4510 is a CPU supervisor with integrated 64‑byte EEPROM memory and four programmable, non‑volatile I/O pins. It communicates via an industry‑standard I²C interface that supports fast‑mode (400 kbps) and standard‑mode (100 kbps).
Key features include an adjustable reset timer (125 ms to 1000 ms), selectable VCC trip points, operation from –40 °C to +85 °C, and low standby current. The device also provides configurable pull‑up resistors on each I/O pin and supports both SRAM‑shadowed and EEPROM memory modes.
