Product details

Overview

DS4510U-15/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 ±15% trip point (4.0–4.24 V), 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-15/T&R datasheet, DS4510U-15/T&R pinout, DS4510U-15/T&R application, or DS4510U-15/T&R equivalent, this page delivers verified technical context, exact pin functions, real-world use cases in RAM-based FPGA configuration and embedded power management, and validated alternative parts with documented functional trade-offs.

Technical Context

The DS4510U-15/T&R implements a voltage-monitoring circuit with fixed 15% V_CC trip threshold (4.0–4.24 V at +25°C), coupled to a programmable reset timer whose delay (125/250/500/1000 ms) is set via two SEEPROM bits (TD1/TD0). Its I²C interface supports both standard-mode (100 kbps) and fast-mode (400 kbps) timing, with open-drain SDA/SCL requiring external pullups.

All four I/O pins (I/O0–I/O3) are bidirectional, feature selectable internal 4.0–6.5 kΩ pullup resistors, and retain their last programmed state in EEPROM on power-up. The RST output is active-low, open-drain, and requires an external pullup; its assertion is triggered either by V_CC dropout below VCCTP or by software write to SWRST bit in Config register.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Trip Point	4.0–4.24 V (±15% of 5 V); ensures reliable reset initiation during brownout conditions in 5 V systems.
Reset Timeout Range	125–1000 ms (four discrete settings); configurable via TD1/TD0 bits to match system boot timing requirements.
I²C Interface Speed	100 kbps (standard) or 400 kbps (fast mode); enables compatibility with legacy and high-speed microcontrollers.
Nonvolatile I/O Pins	4 × bidirectional pins with EEPROM-retained power-on state; eliminates need for external latch or configuration memory.
EEPROM Capacity	64 bytes user EEPROM + 2 bytes SEEPROM + 6 bytes SRAM; stores I/O defaults, reset delay, and application data persistently.
Supply Voltage Range	2.7–5.5 V; supports operation across 3.3 V and 5 V logic domains without level-shifting.
Package	10-pin µSOP (3.0 mm × 3.0 mm, 0.5 mm pitch); surface-mount compatible with high-density PCB layouts.

Pinout & Package

DS4510U-15/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 applications. Pin functions are electrically validated per Maxim's official datasheet Rev 2 (August 2004).

Pin/Terminal	Circuit Role	Design Meaning
A0	I²C slave address select	Sets device address to 1010000b (A0 = 0) or 1010001b (A0 = 1); enables dual-device addressing on same bus.
SDA	I²C bidirectional data line	Open-drain output requiring external pullup; supports multi-master arbitration and clock stretching avoidance.
SCL	I²C clock input	Accepts 100/400 kHz clocks; no internal clock stretching - simplifies timing budget in real-time systems.
VCC	Power supply input	Supplies core logic, EEPROM, and I/O drivers; operates from 2.7 V to 5.5 V with 50–75 µA standby current.
GND	Ground reference	Common return path for all analog and digital circuits; must be low-impedance to ensure accurate V_CC monitoring.
I/O3–I/O0	Programmable NV I/O pins	Bidirectional with internal pullup enable/disable; retain state in EEPROM across power cycles for FPGA profile selection.
RST	Active-low open-drain reset output	Drives CPU reset line; requires external pullup resistor (e.g., 5.6 kΩ) to generate valid logic-high when inactive.

Key Features

Feature	Design Value
±15% V_CC monitoring accuracy	Guaranteed trip window (4.0–4.24 V) ensures deterministic reset behavior under 5 V rail tolerance variations.
Four NV I/O pins with EEPROM retention	Eliminates external latches or configuration PROMs in FPGA bank-switching applications, reducing BOM count.
SRAM-shadowed EEPROM (SEEPROM)	Enables infinite writes to I/O control registers (F4–F7) when SEE=1, avoiding EEPROM wear-out during dynamic reconfiguration.
Software-initiated reset (SWRST)	Allows host MCU to trigger hardware reset via I²C write - critical for watchdog recovery and firmware updates.
Configurable internal I/O pullups (4–6.5 kΩ)	Reduces need for external pullup resistors on I/O lines, saving board area and assembly cost in compact designs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX6816EUK+T	Single-channel pushbutton debouncer with 12 V tolerant inputs; no EEPROM, no I/O expansion, no reset timer.	Limited to simple reset generation; cannot replace DS4510U-15/T&R in FPGA bank-switching or multi-I/O state retention.	Select only for basic manual reset applications where EEPROM and programmable I/O are unnecessary.
TPS3808G15DBVR	Dedicated 5 V supervisor with 1.5% accuracy and 200 ms fixed reset delay; zero I/O pins, no memory, no I²C interface.	Provides higher voltage accuracy but lacks configurability - unsuitable for systems requiring post-power-up I/O reprogramming.	Choose when precise 5 V monitoring is critical and I/O expansion or EEPROM storage is handled elsewhere.

Compared with MAX6816EUK+T and TPS3808G15DBVR, DS4510U-15/T&R uniquely integrates voltage supervision, EEPROM-backed I/O state retention, and I²C programmability in one 10-pin µSOP - enabling single-chip solutions for FPGA configuration, embedded power sequencing, and dynamic peripheral control where alternatives require multiple discrete components.

FAQ

What is the V_CC trip point tolerance for DS4510U-15/T&R?

The DS4510U-15/T&R has a guaranteed ±15% trip point tolerance relative to nominal 5 V supply, resulting in a VCCTP range of 4.0 V to 4.24 V at +25°C. This specification is tested and characterized across -40°C to +85°C operating temperature, with typical drift of ±0.1 V over full temperature range per Maxim's DS4510 datasheet Rev 2.

Does DS4510U-15/T&R support I²C fast-mode operation?

Yes, DS4510U-15/T&R fully supports I²C fast-mode operation at 400 kbps, as confirmed in its AC Electrical Characteristics table. It also maintains backward compatibility with standard-mode (100 kbps) timing, allowing integration with legacy microcontrollers without timing redesign.

How many write cycles does the EEPROM in DS4510U-15/T&R support?

The 64-byte EEPROM in DS4510U-15/T&R is rated for 50,000 write cycles at +70°C, as specified in the Nonvolatile Memory Characteristics section. SEEPROM registers (F2–F3) do not consume EEPROM cycles when SEE=1, preserving endurance for critical I/O state storage.

Is an external pullup resistor required for the RST pin of DS4510U-15/T&R?

Yes, DS4510U-15/T&R's RST pin is an open-drain output and requires an external pullup resistor (typically 4.7–5.6 kΩ to V_CC) to generate a valid logic-high level when inactive. This is explicitly stated in the Pin Description and Typical Operating Circuit sections of the datasheet.

Can DS4510U-15/T&R retain I/O pin states across power cycles?

Yes, DS4510U-15/T&R stores the last programmed state of all four I/O pins (I/O0–I/O3) in EEPROM. During power-up, these values are automatically recalled once V_CC exceeds 2.0 V, ensuring deterministic I/O behavior without host MCU intervention - a key feature for FPGA bank selection and industrial I/O configuration.
