DATASHEET X5043, X5045 FN8126 Rev 3.00 September 23, 2015 4K, 512 x 8 Bit CPU Supervisor with 4K SPI EEPROM These devices combine four popular functions, Power-on Reset Control, Watchdog Timer, Supply Voltage Supervision, and Block Lock Protect Serial EEPROM Memory in one package. This combination lowers system cost, reduces board space requirements, and increases reliability. Applying power to the device activates the power-on reset circuit which holds RESET/RESET active for a period of time. This allows the power supply and oscillator to stabilize before the processor executes code. The Watchdog Timer provides an independent protection mechanism for microcontrollers. When the microcontroller fails to restart a timer within a selectable time out interval, the device activates the RESET/RESET signal. The user selects the interval from three preset values. Once selected, the interval does not change, even after cycling the power. The device’s low VCC detection circuitry protects the user’s system from low voltage conditions, resetting the system when VCC falls below the minimum VCC trip point. RESET/RESET is asserted until VCC returns to proper operating level and stabilizes. Four industry standard VTRIP thresholds are available, however, Intersil’s unique circuits allow the threshold to be reprogrammed to meet custom requirements or to fine-tune the threshold for applications requiring higher precision. Features • Low VCC Detection and Reset Assertion - Four standard reset threshold voltages 4.63V, 4.38V, 2.93V, 2.63V - Re-program low VCC reset threshold voltage using special programming sequence. - Reset signal valid to VCC = 1V • Selectable Time Out Watchdog Timer • Long Battery Life with Low Power Consumption - 3.3V, IOH = –1.0mA VCC - 0.8 V VOH2 Output HIGH Voltage (SO) 2V < VCC  3.3V, IOH = –0.4mA VCC - 0.4 V VOH3 Output HIGH Voltage (SO) VCC  2V, IOH = –0.25mA VCC - 0.2 V VOLRS Output LOW Voltage (RESET, RESET) IOL = 1mA VIL VIH Capacitance CIN(2) V TA = +25°C, f = 1MHz, VCC = 5V SYMBOL COUT(2) 0.4 TEST Output Capacitance (SO, RESET, RESET) Input Capacitance (SCK, SI, CS, WP) CONDITIONS MAX UNIT VOUT = 0V 8 pF VIN = 0V 6 pF NOTES: 1.
