Replacement verdict
Compatible functional replacement candidate
The ADM1062ACPZ and ADM1063ACP are both Analog Devices Super Sequencers in the same 40-lead LFCSP package with a comparable supply voltage range and I2C/SMBus interface, making them a plausible functional replacement pairing. However, they differ in on-chip DAC resolution and the number of programmable output drivers, so the ADM1063ACP should be validated against the ADM1062ACPZ's specific margining and sequencing requirements before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADM1062ACPZ | ADM1063ACP | Why it matters |
|---|---|---|---|
| Number of Supervisory Inputs | 10 inputs | 10 inputs | Determines how many supply rails can be monitored simultaneously; identical here so both cover the same monitoring capacity. |
| Number of Programmable Output Drivers | 10 (PDO) | 10 (PDO) | Sets how many external enable/sequencing signals can be driven; equal count means equivalent sequencing fan-out. |
| Supply Voltage Range (VCC) | 3.0 V to 14.4 V | 3.0 V to 14.4 V | Defines the operating supply window of the supervisor itself; matching ranges allow drop-in use in the same power domain. |
| Integrated ADC Resolution | 12-bit ADC | 12-bit ADC | Affects voltage measurement accuracy for margining and fault logging; identical resolution gives equivalent measurement precision. |
| Nonvolatile Fault Logging (Black Box) | Yes | Yes | Enables capture of fault events to EEPROM for post-mortem diagnostics; both support it, so diagnostic capability is preserved. |
| Sequencing Engine (SE) | Yes | Yes | Provides programmable power-up/down sequencing state machine; both include it, so sequencing behavior is equivalent. |
| Package / Pin Count | 40-lead LFCSP (6x6 mm) | 40-lead LFCSP (6x6 mm) | Footprint and pinout compatibility determine whether a part can be swapped on an existing PCB; identical package supports direct substitution. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Defines the environmental envelope for reliable operation; matching ranges mean the same application environments are supported. |
| Communication Interface | SMBus/I2C (PMBus-compatible) | SMBus/I2C (PMBus-compatible) | Determines how the host configures and reads the device; identical interface allows reuse of the same firmware and bus topology. |

Frequently asked questions
What are the ADM1062ACPZ and ADM1063ACP?
The ADM1062ACPZ and ADM1063ACP are both Analog Devices Super Sequencers (programmable power supply sequencers with integrated supervisory and margining functions) in a 40-lead LFCSP package. The ADM1062 integrates a 12-bit ADC for voltage readback and margining, while the ADM1063 provides a similar sequencing and supervision core but does not include the ADC-based margining/readback function.
What is the key functional difference between the ADM1062ACPZ and ADM1063ACP?
The primary difference is that the ADM1062ACPZ includes a 12-bit successive-approximation ADC with a multiplexer for monitoring and margining supply rails, whereas the ADM1063ACP does not include this ADC/margining capability. Both devices provide programmable supply sequencing, undervoltage/overvoltage supervision, and fault handling via the same Super Sequencer architecture.
Are the ADM1062ACPZ and ADM1063ACP pin-compatible?
Both devices are offered in the same 40-lead LFCSP (CP-40) package, but pin compatibility must be confirmed against the respective Analog Devices datasheets, because the ADM1062 uses additional pins/functions for its ADC and margining features. A direct drop-in substitution should only be made after verifying pin functions and the PCB land pattern against the manufacturer documentation.
What supply voltage range do these devices support?
Both the ADM1062 and ADM1063 operate from a single VCC supply in the 3.0 V to 14.4 V range, with the on-chip regulators providing the internal low-voltage rails required by the sequencing and supervision circuitry. Designers should confirm the exact limits in the Analog Devices datasheet for the specific grade and package.
How many supply rails can each device sequence and supervise?
Both the ADM1062ACPZ and ADM1063ACP provide ten programmable input channels (VH/VP pins) for supply supervision and sequencing, allowing monitoring and sequencing of up to ten power rails. The ADM1062 additionally allows these inputs to be routed to its 12-bit ADC for voltage readback and margining.
What communication interface do the ADM1062ACPZ and ADM1063ACP use?
Both devices use an I2C-compatible (SMBus) two-wire serial interface for configuration, programming, and status readback. The ADM1062 also allows ADC results and margining adjustments to be accessed over this interface.
Can the ADM1063ACP be used as a replacement for the ADM1062ACPZ?
Only if the design does not require the ADM1062's ADC-based voltage readback and margining functions. The ADM1063ACP provides the sequencing and supervision core but lacks the ADC/margining block, so substituting it for the ADM1062ACPZ would remove those capabilities. Any substitution must be validated against the Analog Devices datasheets and the target design requirements.
What are typical applications for these Super Sequencers?
Both devices are intended for sequencing and supervising multiple power rails in systems such as telecommunications equipment, servers, storage, industrial control, and FPGA/ASIC-based boards, where controlled power-up/power-down ordering and fault monitoring are required. The ADM1062's ADC additionally supports voltage margining and readback in such systems.
