Analog Devices Inc./Maxim Integrated DS4510U-5+T&R

Overview

DS4510U-5+T&R 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 monitors 5V supply at ±5% accuracy (4.5–4.75 V trip), provides adjustable reset timeout (125–1000 ms), and retains I/O states across power cycles for FPGA bank switching and industrial control systems.

For engineers reviewing the DS4510U-5+T&R datasheet, DS4510U-5+T&R pinout, DS4510U-5+T&R application, or DS4510U-5+T&R equivalent, this page delivers verified functional identity, confirmed I²C timing compliance, validated 10-pin µSOP package mapping, exact VCC trip point specification, and real-world use cases in RAM-based FPGA configuration and embedded power management.

Technical Context

The DS4510U-5+T&R implements a voltage-monitoring circuit with hysteresis-free 5% VCC trip detection (4.5 V min, 4.75 V max) and an independent programmable reset timer controlled via SEEPROM register F1 (TD1/TD0 bits). Its I²C interface supports both standard-mode (100 kbps) and fast-mode (400 kbps) operation with guaranteed tBUF ≥1.3 µs and tHD:STA ≥0.6 µs.

All four I/O pins (I/O0–I/O3) are bidirectional, open-drain-capable, and feature individually controllable internal pullup resistors (4.0–6.5 kΩ) set via register F0. Their power-on state is stored in EEPROM and recalled after VCC exceeds 2.0 V; during power-down, state retention holds until VCC drops below 1.9 V.

FAQ

What is the exact VCC trip point tolerance for DS4510U-5+T&R?

The DS4510U-5+T&R has a guaranteed ±5% VCC trip point tolerance, specified as 4.5 V (minimum), 4.625 V (typical), and 4.75 V (maximum) at -40°C to +85°C. This tight tolerance ensures reliable detection of 5 V rail undervoltage events without external calibration, and is factory-trimmed - not dependent on external resistors or temperature compensation circuits. DS4510U-5+T&R maintains this accuracy across its full operating temperature range.

Does DS4510U-5+T&R support both standard-mode and fast-mode I²C communication?

Yes, DS4510U-5+T&R fully supports I²C standard-mode (100 kbps) and fast-mode (400 kbps) operation. Its AC electrical characteristics specify tLOW ≥1.3 µs and tHIGH ≥0.6 µs for fast-mode, and it complies with I²C bus timing requirements including tBUF ≥1.3 µs and tHD:STA ≥0.6 µs. DS4510U-5+T&R does not implement clock stretching, making it compatible with all standard I²C masters without timing negotiation overhead.

How many write cycles are guaranteed for the EEPROM in DS4510U-5+T&R?

The 64-byte EEPROM in DS4510U-5+T&R is guaranteed for 50,000 write cycles at +70°C, as specified in the Nonvolatile Memory Characteristics table. This rating applies only to writes to the main EEPROM block (addresses 00h–3Fh); writes to SEEPROM registers (F2h–F7h) with SEE=1 do not consume EEPROM endurance. DS4510U-5+T&R implements page-write architecture (8-byte pages), and partial-page writes still incur full-page wear - so optimal usage minimizes single-byte updates across pages.

Can DS4510U-5+T&R drive LEDs directly using its I/O pins?

DS4510U-5+T&R I/O pins (I/O0–I/O3) support up to 4 mA sink current with VOLIOX ≤0.4 V, making them suitable for driving low-current LEDs (e.g., 2 mA typical) when configured as open-drain outputs with external anode pullup. Each pin includes a selectable internal pullup resistor (4.0–6.5 kΩ), but for LED current limiting, an external series resistor is required. DS4510U-5+T&R does not support source-driving or high-current loads - its I/O structure is optimized for logic-level expansion, not power delivery.

Is the RST output of DS4510U-5+T&R push-pull or open-drain?

The RST output of DS4510U-5+T&R is strictly open-drain, requiring an external pullup resistor (typically 4.7–5.6 kΩ) to achieve valid high logic levels. This design allows wired-OR reset bus configurations and voltage-level translation across mixed-supply systems. The datasheet specifies VOLRST ≤0.4 V at 10 mA sink, confirming its open-drain driver strength. DS4510U-5+T&R does not offer a push-pull RST option - all variants in the DS4510 family share this output topology.
