Product details

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 technical context, exact pin functions, real-world use cases in RAM-based FPGA configuration and embedded peripherals, and validated alternative parts with documented functional differences.

Technical Context

The DS4510U-5/T&R implements a voltage-monitoring circuit with precise 5% V_CC trip point (4.5–4.75 V), a programmable reset timer controlled via SEEPROM register F1 (TD1/TD0 bits), and an I²C slave interface supporting standard- and fast-mode timing. Its RST output is open-drain, requiring external pullup.

All four I/O pins (I/O0–I/O3) are bidirectional, NV-configurable via SEEPROM shadow registers (F4–F7), with individually enabled internal pullups (4.0–6.5 kΩ) controlled by register F0. The device uses SRAM-shadowed EEPROM (SEEPROM) architecture-enabling either infinite SRAM-like writes or persistent EEPROM state retention based on the SEE bit in Config register F9.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Trip Point	4.5 V (min), 4.625 V (typ), 4.75 V (max) - ensures reliable 5V system reset initiation within ±5% tolerance.
RST Active Time	125–1000 ms (configurable in 4 steps) - supports flexible power-up sequencing for FPGAs and microcontrollers.
I²C Interface Speed	100 kbps (standard mode) or 400 kbps (fast mode) - enables compatibility with legacy and high-speed controllers without protocol translation.
EEPROM Capacity	64 bytes (non-shadowed, true EEPROM) - stores critical system configuration data with guaranteed 50,000 write cycles at +70°C.
I/O Pullup Resistance	4.0–6.5 kΩ (typ 5.0 kΩ) - provides robust weak-pull logic levels compatible with 3.3V/5V I/O domains without external resistors.
Supply Voltage Range	2.7 V to 5.5 V - allows operation across wide-input industrial and battery-backed systems.
Standby Current	50–75 µA at V_CC = 5.0 V - minimizes quiescent power in always-on supervisory functions.

Pinout & Package

DS4510U-5/T&R is housed in a 10-pin µSOP package (3.0 mm × 3.0 mm, 0.5 mm pitch), optimized for space-constrained industrial and portable designs.

Pin/Terminal	Circuit Role	Design Meaning
A0	I²C address select input	Sets slave address to 1010000b (A0 = 0) or 1010001b (A0 = 1); enables dual-device addressing on same bus.
SDA	I²C bidirectional data line	Open-drain output requires external pullup; supports multi-master arbitration and clock stretching-free operation.
SCL	I²C clock input	Accepts standard/fast-mode clocks up to 400 kHz; no internal clock stretching required.
V_CC	Power supply input	Supplies core logic, EEPROM, and I/O drivers; operates from 2.7 V to 5.5 V with full functionality.
GND	Ground reference	Primary return path for all analog and digital currents; must be low-impedance for stable reset threshold.
I/O3–I/O0	Programmable NV I/O pins	Bidirectional with configurable pullup/pulldown; retain last state through power cycles when SEEPROM configured as EEPROM.
RST	Active-low open-drain reset output	Drives microcontroller/FPGA reset line; requires external pullup resistor (typically 4.7 kΩ) to V_CC.

Key Features

Feature	Design Value
5% accurate 5V supervision	Guarantees reset assertion before 5V rail drops below 4.5 V - prevents erratic MCU/FPGA behavior during brownout.
Four NV I/O pins with internal pullups	Eliminates four external 4.7 kΩ resistors and associated PCB area; reduces BOM count and layout complexity.
64-byte user EEPROM + SEEPROM registers	Stores FPGA configuration profiles, calibration data, or boot settings; SEEPROM (F2–F3, F4–F7) enables SRAM-speed writes without wearing EEPROM.
Configurable reset timeout (125–1000 ms)	Matches diverse power-up delays - e.g., 125 ms for fast-boot MCUs, 1000 ms for slow-ramping FPGA supplies.
I²C-compatible interface (100/400 kbps)	Integrates seamlessly with existing I²C infrastructure; no additional level-shifting or protocol conversion needed.

Equivalent & Alternatives

The following parts are listed as comparable options for similar CPU supervisor with I/O expansion applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX6816EUK+T	Single-channel pushbutton debouncer with 12ms filter; no EEPROM, no programmable I/O, no reset timer.	Limited to simple reset generation from mechanical switches; cannot store FPGA profiles or manage multi-pin I/O states.	Select only for basic manual reset applications lacking memory or I/O expansion needs.
TPS3808G125DBVR	Dedicated 1.25V supervisor with fixed 200ms delay; no I²C interface, no EEPROM, no user I/O pins.	Designed for low-voltage ASIC/MCU monitoring only; lacks configurability and peripheral control capability.	Choose when supervising sub-1.8V rails where DS4510U-5/T&R's 2.7–5.5V range is excessive.

Compared with MAX6816EUK+T and TPS3808G125DBVR, DS4510U-5/T&R uniquely combines 5V supervision, nonvolatile I/O state retention, and EEPROM-based configuration storage - making it irreplaceable for FPGA profile switching and multi-function embedded supervisors requiring persistent state.

FAQ

What is the V_CC trip point tolerance for DS4510U-5/T&R?

The DS4510U-5/T&R has a guaranteed ±5% V_CC trip point tolerance, specified as 4.5 V (min), 4.625 V (typ), and 4.75 V (max) at -40°C to +85°C. This tight tolerance ensures reliable reset assertion before 5V systems enter unstable operating regions, and is factory-trimmed - no external calibration is required. DS4510U-5/T&R maintains this accuracy across its full temperature range without derating.

How does the DS4510U-5/T&R handle I/O pin state retention across power cycles?

The DS4510U-5/T&R retains I/O pin states across power cycles using its SEEPROM architecture: when the SEE bit (Config register F9) is cleared, writes to I/O control registers (F4–F7) are stored in true EEPROM, and recalled at power-up. I/O pins remain high-impedance until V_CC exceeds ~2.0 V, then assume their stored state. DS4510U-5/T&R guarantees this behavior across 50,000 EEPROM write cycles at +70°C.

Can DS4510U-5/T&R be used with 3.3V I²C masters?

Yes - DS4510U-5/T&R supports mixed-voltage I²C operation. Its SDA and SCL inputs accept VIH ≥ 0.7×V_CC and VIL ≤ 0.3×V_CC; with V_CC = 5.0 V, VIH(min) = 3.5 V, which is compatible with 3.3V logic high levels. The DS4510U-5/T&R's open-drain SDA output also interfaces safely with 3.3V pullups. No level shifter is needed when V_CC = 5V and master operates at 3.3V.

What is the maximum EEPROM write time for DS4510U-5/T&R?

The DS4510U-5/T&R requires up to 20 ms (typ 10 ms) to complete an EEPROM page write after a STOP condition, as specified in the Nonvolatile Memory Characteristics table. During this time, the device does not acknowledge its I²C address - enabling "acknowledge polling" to detect completion. DS4510U-5/T&R's 64-byte EEPROM is organized in eight 8-byte pages; each write transaction affects only one page.

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, as confirmed in the Pin Description and Detailed Description sections. It requires an external pullup resistor (typically 4.7 kΩ to V_CC) to assert a logic-high level. This architecture allows wired-OR reset bus sharing with other supervisors or processors - a key requirement in complex multi-rail systems where DS4510U-5/T&R is often deployed.
