Analog Devices Inc./Maxim Integrated DS4510U-10

Overview

DS4510U-10 from Maxim Integrated is a CPU supervisor IC with integrated 64-byte EEPROM, four nonvolatile programmable I/O pins, and I²C interface (100/400 kbps). It provides 4.25V–4.49V V_CC trip point (10% tolerance), 125ms–1000ms adjustable reset timeout, and operates from 2.7V to 5.5V supply. Used in FPGA bank switching, industrial controls, and PC peripherals for power monitoring and state retention across power cycles.

For engineers reviewing the DS4510U-10 datasheet, DS4510U-10 pinout, DS4510U-10 application, or DS4510U-10 equivalent, key selection considerations include its 10-pin µSOP package, open-drain RST output, internal I/O pullup resistors (4.0–6.5 kΩ), SEEPROM-configurable I/O power-on behavior, and EEPROM endurance (50,000 cycles at +70°C).

Technical Context

The DS4510U-10 implements a voltage-monitoring supervisor with programmable reset delay via two-bit TD1/TD0 register (F1h), enabling four discrete timeout values (125/250/500/1000 ms). Its I²C interface supports both standard- and fast-mode timing, with SDA/SCL rise/fall times specified up to 400 pF bus capacitance.

All four I/O pins (I/O0–I/O3) are bidirectional, open-collector with individually controllable internal pullups (via F0h) and pulldown transistors (via F4h–F7h). Their power-on states are stored in EEPROM and recalled after V_CC exceeds 2.0V; during power-down, states persist until V_CC falls below 1.9V.

FAQ

What is the V_CC trip point specification for DS4510U-10?

The DS4510U-10 has a nominal V_CC trip point of 4.375V, with minimum and maximum values of 4.25V and 4.49V respectively, corresponding to a 10% tolerance around 4.375V. This specification is guaranteed over the full operating temperature range of -40°C to +85°C and applies specifically to the DS4510U-10 variant - not the DS4510U-5 or DS4510U-15 versions.

How does the DS4510U-10 handle I/O pin state retention across power cycles?

The DS4510U-10 stores the power-on state of each I/O pin (I/O0–I/O3) in its internal EEPROM. During power-up, when V_CC exceeds 2.0V (typical), the last programmed state is automatically recalled and applied to the pins. On power-down, the state remains active until V_CC drops below 1.9V (typical), ensuring glitch-free transitions and reliable system boot sequencing for DS4510U-10 deployments.

Can DS4510U-10 operate with a 3.3V supply?

Yes, DS4510U-10 supports supply voltages from 2.7V to 5.5V, making it fully compatible with 3.3V systems. Its V_CC trip point remains fixed at 4.25V–4.49V, so it functions as a 5V rail monitor even when powered from 3.3V - provided the monitored rail is separate and within spec. All I/O logic levels (VIH/VIL) and EEPROM operations remain valid across the entire supply range.

What is the purpose of the SEE bit in the DS4510U-10 Config register?

The SEE bit (bit 4 of Config register F9h) controls whether writes to SEEPROM registers (F2h–F7h) behave as SRAM (SEE=1) or EEPROM (SEE=0). When SEE=1, writes are volatile and infinitely repeatable without wearing the EEPROM; when SEE=0, changes persist across power cycles. This allows DS4510U-10 to optimize for speed during runtime I/O control or reliability during configuration storage.

Is an external pullup resistor required for the RST pin of DS4510U-10?

Yes, the RST pin of DS4510U-10 is an open-drain output and requires an external pullup resistor to generate a valid high-level signal. The datasheet recommends a 5.6kΩ resistor for typical 5V operation. Without this pullup, RST cannot assert a logic-high state, compromising system reset functionality - a mandatory design requirement for all DS4510U-10 implementations.
