® X5163, X5165 Data Sheet June 1, 2006 FN8128.3 CPU Supervisor with 16Kbit SPI EEPROM Description 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 can execute 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. Five 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 • Selectable watchdog timer • Low VCC detection and reset assertion - Five standard reset threshold voltages - Re-program low VCC reset threshold voltage using special programming sequence - Reset signal valid to VCC = 1V • Determine watchdog or low voltage reset with a volatile flag bit • Long battery life with low power consumption - 3.3V, IOL = 2.1mA 2V < VCC ≤ 3.3V, IOL = 1mA VCC ≤ 2V, IOL = 0.5mA VCC > 3.3V, IOH = –1.0mA 2V < VCC ≤ 3.3V, IOH = –0.4mA VCC ≤ 2V, IOH = –0.25mA IOL = 1mA VCC - 0.8 VCC - 0.4 VCC - 0.2 0.4 V Capacitance TA = +25°C, f = 1MHz, VCC = 5V SYMBOL COUT CIN NOTES: 1.
