Product details
Overview
X5163P from Intersil is a CPU supervisor IC integrating power-on reset control, watchdog timer, supply voltage supervision, and 16Kbit SPI EEPROM in a single 8-lead PDIP package. It asserts active-low RESET at VCC ≥ 1V, provides selectable watchdog timeout (200ms/600ms/1.4s), supports 2.7–5.5V operation, and features reprogrammable VTRIP threshold (4.5–4.75V for X5163PZ-4.5A) for microcontroller-based embedded systems requiring reliable power sequencing and nonvolatile configuration storage.
For engineers reviewing the X5163P datasheet, X5163P pinout, X5163P application, or X5163P equivalent, this device serves as a system-level reliability component for industrial controllers, medical instrumentation, and telecom infrastructure where deterministic reset behavior, brownout protection, and in-circuit programmable EEPROM are required.
Technical Context
The X5163P implements a dual-function CS/WDI pin that enables SPI communication and resets the watchdog timer on HIGH-to-LOW transitions. Its reset logic combines power-on reset (active until VCC stabilizes ≥200ms above VTRIP) and low-voltage detection (RESET asserted when VCC drops below 4.5V nominal, with 20mV hysteresis).
Internally, it integrates a 16Kbit SPI EEPROM organized as 2K × 8, supporting 32-byte page writes with self-timed 5ms typical write cycles. The Status Register includes volatile WIP and flag bits plus nonvolatile WD0/WD1 (watchdog timeout selection), BL0/BL1 (block lock protection), and WPEN (in-circuit ROM mode enable).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VTRIP Threshold | 4.5–4.75V - precisely configurable reset voltage for 5V systems with ±25mV repeatability after programming |
| Watchdog Timeout | 200ms / 600ms / 1.4s - selectable via nonvolatile WD0/WD1 bits; remains fixed across power cycles |
| EEPROM Capacity | 16Kbit (2K × 8) - supports firmware versioning, calibration data, and device configuration storage |
| Supply Range | 2.7–5.5V - operates across wide input range while maintaining valid RESET down to VCC = 1V |
| Standby Current | <1µA (WDT off) / <50µA (WDT on) - enables ultra-low-power battery-backed applications |
| SPI Interface | 2MHz max clock rate, modes 0,0 and 1,1 - compatible with standard microcontroller SPI peripherals |
| Reset Output | Active-low open-drain RESET - drives external reset lines or pull-up networks without internal current limiting |
Pinout & Package
Package: 8-lead PDIP (RoHS-compliant, MDP0031 footprint). Lead finish: 100% matte tin. Through-hole wave solder only; not for reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: CS/WDI | Chip Select / Watchdog Input | Enables SPI interface when LOW; restarts watchdog timer on HIGH→LOW transition |
| 2: SO | Serial Output | Push-pull data output; shifts out EEPROM or status register contents on SCK falling edge |
| 3: WP | Write Protect | Hardware lock for Status Register when WPEN=1; disables nonvolatile writes to WD/BL/WPEN bits |
| 4: VSS | Ground | Reference return path for all internal circuits and I/O pins |
| 5: SI | Serial Input | Latches opcode, address, and data on SCK rising edge; MSB-first protocol |
| 6: SCK | Serial Clock | Controls timing of SPI transfers; rising edge latches input, falling edge clocks output |
| 7: RESET/RESET | Reset Output | Open-drain active-low signal asserting during power-up, brownout, or watchdog timeout |
| 8: VCC | Supply Voltage | Primary power input; powers all internal blocks including EEPROM and reset circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Reprogrammable VTRIP | Threshold adjustable via VP-programming sequence to meet custom 4.5–4.75V requirements with ±25mV repeatability |
| Block Lock™ EEPROM Protection | Nonvolatile BL0/BL1 bits enable hardware-level write protection of 0%, 25%, 50%, or 100% of 16Kbit array |
| Volatile Reset Flag | Flag bit distinguishes watchdog-initiated reset from low-voltage reset-critical for fault diagnostics |
| In-Circuit Programmable ROM Mode | WP pin + WPEN bit combination locks Status Register against accidental writes post-manufacturing |
| Low-Voltage Valid Reset | RESET remains functional down to VCC = 1V, ensuring reliable assertion even during deep brownout conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPU supervisor with integrated EEPROM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6361KA29+T | Fixed 2.93V reset threshold; no VTRIP reprogramming; 16Kbit EEPROM; 3.0–5.5V supply | Lacks field-adjustable trip point; suitable only for designs with stable 3V rails | Select when VTRIP adjustment is unnecessary and RoHS-compliant TDFN-8 package is preferred |
| STM6805RWD3F | Fixed 4.63V reset; no integrated EEPROM; 1.8–5.5V supply; push-pull RESET output | Requires external EEPROM; higher standby current (2.5µA vs. X5163P's 1µA) | Choose when board space permits separate EEPROM and push-pull reset drive is mandatory |
Compared with MAX6361KA29+T and STM6805RWD3F, the X5163P uniquely delivers field-reprogrammable VTRIP, integrated 16Kbit EEPROM with Block Lock™, and sub-1µA standby current-making it optimal for cost-sensitive, space-constrained 5V systems requiring post-deployment voltage threshold tuning.

FAQ
What is the exact VTRIP voltage range for X5163P?
The X5163P variant X5163PZ-4.5A has a factory-programmed VTRIP range of 4.5V to 4.75V, with nominal trip at 4.63V and 20mV hysteresis. This threshold is reprogrammable using the VP-programming sequence described in FN8128 Rev 4.00, enabling fine-tuning for specific 5V rail tolerances. The X5163P datasheet confirms this value applies exclusively to the X5163PZ-4.5A ordering option.
Does X5163P support both active-low and active-high reset outputs?
No, the X5163P provides only an active-low open-drain RESET output (pin 7). The datasheet explicitly identifies X5163 as the active-low variant and X5165 as the active-high counterpart. Since the part number is X5163P, it is strictly active-low; no internal configuration or external circuitry can convert it to active-high operation.
How does the watchdog timer function on X5163P?
The X5163P watchdog timer monitors the CS/WDI pin (pin 1) and triggers RESET if no HIGH-to-LOW transition occurs within the selected timeout period-200ms, 600ms, or 1.4s-as set by nonvolatile WD0/WD1 bits. The timer resets on each CS/WDI edge and remains enabled across power cycles unless disabled via Status Register programming. Its operation is independent of SPI activity.
Can the EEPROM in X5163P be written during normal operation without halting the MCU?
Yes, the X5163P EEPROM supports concurrent read/write operations: the MCU can execute code while the X5163P performs self-timed 5ms write cycles. Write Enable Latch (WEL) must be set first via WREN instruction, and the Status Register's WIP bit indicates busy state. Page writes (up to 32 bytes) minimize bus occupancy versus byte-by-byte writes.
What package type and lead finish does X5163P use?
The X5163P is supplied in an 8-lead PDIP package (MDP0031 drawing), RoHS-compliant with 100% matte tin plating. Per FN8128 Rev 4.00, these Pb-free PDIPs are qualified only for through-hole wave soldering-not reflow-and are intended as legacy replacements for discontinued SOIC variants like X5163S8Z-4.5A.
