Product details
Overview
DS4510U-15 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 operates from -40°C to +85°C in 10-pin µSOP. Used in FPGA bank switching and industrial control systems for state retention and power-on configuration.
For engineers reviewing the DS4510U-15 datasheet, DS4510U-15 pinout, DS4510U-15 application, or DS4510U-15 equivalent, this page delivers verified technical context, exact pin functions, real-world use scenarios, and validated alternative parts - all grounded in Maxim's official DS4510 family documentation and electrical specifications.
Technical Context
The DS4510U-15 implements a voltage-monitoring circuit with hysteresis-based 5V supervision (VCCTP = 4.0–4.24 V), an I²C-compatible serial interface supporting both standard- and fast-mode timing, and SRAM-shadowed EEPROM (SEEPROM) architecture enabling configurable volatile/NV behavior for I/O control registers. Its RST output is open-drain with 10 mA sink capability.
Four bidirectional I/O pins (I/O0–I/O3) feature individually controllable internal pullup resistors (4.0–6.5 kΩ), programmable pulldown transistors, and power-cycle state retention via EEPROM-backed configuration. The device uses A0 pin to select between two I²C slave addresses (1010000b / 1010001b) and supports acknowledge polling during EEPROM writes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Trip Point | 4.0–4.24 V (±15% tolerance at 5V nominal; enables reliable brownout detection) |
| Reset Timeout Range | 125–1000 ms (programmable via SEEPROM register F1; supports flexible system initialization timing) |
| I²C Interface Speed | 100 kHz (standard-mode) or 400 kHz (fast-mode); no clock stretching required |
| EEPROM Capacity | 64 bytes user EEPROM (non-shadowed; guaranteed 50,000 write cycles at +70°C) |
| Nonvolatile I/O Pins | 4 × bidirectional I/O (I/O0–I/O3) with EEPROM-stored power-on states and selectable internal pullups |
| Supply Voltage Range | 2.7–5.5 V (supports mixed-voltage systems including 3.3V and 5V domains) |
| Standby Current | 50–75 µA at VCC = 5.0 V (enables low-power operation in always-on monitoring applications) |
Pinout & Package
DS4510U-15 is housed in a 10-pin µSOP package (2.1 mm × 3.0 mm, 0.5 mm pitch), thermally optimized for surface-mount assembly and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0 | I²C address input | Selects slave address: 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 hot insertion without VCC dependency (per Note 2) |
| SCL | I²C clock input | CMOS-compatible input; no clock stretching; rise/fall times ≤300 ns into ≤400 pF load |
| VCC | Power supply input | Accepts 2.7–5.5 V; powers internal reference, logic, and I/O drivers; trip point referenced to this rail |
| GND | Ground reference | Primary return path for all analog and digital circuits; must be low-impedance connection |
| I/O3–I/O0 | Programmable NV I/O pins | Bidirectional with configurable pullup/pulldown; state retained across power cycles via EEPROM; high-impedance until VCC > 2.0 V |
| RST | Active-low reset output | Open-drain output; requires external pullup resistor (e.g., 5.6 kΩ); sinks up to 10 mA during assertion |
Key Features
| Feature | Design Value |
|---|---|
| Configurable reset timeout | Four discrete delays (125/250/500/1000 ms) selected by TD1/TD0 bits in register F1 - eliminates need for external RC timing networks |
| SRAM-shadowed EEPROM (SEEPROM) | Registers F2–F7 support SEE-bit-controlled behavior: SRAM mode for infinite writes (I/O expansion), EEPROM mode for power-on state persistence |
| Integrated I/O pullup resistors | Four 4.0–6.5 kΩ internal pullups (per I/OX), individually enabled via F0 register - reduces BOM count and PCB footprint |
| Power-cycle state tracking | EEPROM stores I/O configurations and reset delay settings; recalled automatically after VCC exceeds 2.0 V - maintains system profile across cold starts |
| I²C bus compatibility | Fully compliant with I²C specification; supports repeated start, acknowledge polling, and multi-byte page writes (up to 8 bytes/page) |
Applications
| RAM-Based FPGA Bank Switching | Industrial Control Systems |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPU supervisor with NV I/O applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UT46D3+ | Single fixed 4.63 V reset threshold; no EEPROM or I/O pins; SOT23-3 package | Only provides basic reset generation - lacks programmability, memory, and I/O expansion capability | Choose only if application requires minimal, low-cost reset-only function without configuration storage or GPIO needs. |
| TPS3808G15DBVR | Adjustable reset threshold (via external resistor); no EEPROM or I/O; 6-pin SOT23; 200 ms fixed timeout | Supports threshold tuning but offers no nonvolatile state retention or parallel I/O extension | Select when precise trip-point adjustment is needed and system state persistence is handled elsewhere (e.g., MCU flash). |
Compared with MAX6326UT46D3+ and TPS3808G15DBVR, DS4510U-15 uniquely integrates voltage supervision, EEPROM, and programmable I/O in one 10-pin µSOP - delivering functional consolidation unattainable with either alternative, making it optimal for space- and BOM-constrained designs requiring persistent configuration.

FAQ
What is the VCC trip point tolerance for DS4510U-15?
The DS4510U-15 has a ±15% VCC trip point tolerance, resulting in a guaranteed detection range of 4.0 V to 4.24 V at nominal 5 V supply. This is factory-trimmed and specified over -40°C to +85°C. Unlike DS4510U-5 (±5%) or DS4510U-10 (±10%), the DS4510U-15 variant targets applications where wider supply variation is expected, such as legacy 5V rails with aging regulators.
How does the DS4510U-15 handle I/O pin state retention across power cycles?
The DS4510U-15 retains I/O pin states across power cycles by storing configuration bits (I/O control, pullup enable) in its internal EEPROM. During power-up, once VCC exceeds ~2.0 V, the device automatically recalls the last-written values from EEPROM and applies them to I/O0–I/O3. This behavior is independent of the SEE bit setting, which only affects SEEPROM registers (F2–F7), not the core I/O configuration.
Can DS4510U-15 operate with a 3.3V supply?
Yes, DS4510U-15 supports supply voltages from 2.7 V to 5.5 V, making it fully compatible with 3.3 V systems. Its VCC trip point remains fixed at 4.0–4.24 V, so it will assert reset if VCC drops below that threshold - meaning it supervises the 5V rail even when powered from 3.3V. For true 3.3V rail monitoring, a different variant (e.g., DS4510U-33) would be required, but DS4510U-15 itself functions correctly at 3.3V VCC.
What is the maximum I²C clock frequency supported by DS4510U-15?
The DS4510U-15 supports I²C fast-mode operation up to 400 kHz, as well as backward-compatible standard-mode at 100 kHz. Its AC timing parameters (tLOW, tHIGH, tSU:DAT, etc.) are fully specified for both modes. No clock stretching is implemented, simplifying master-side timing design. Bus capacitance must remain ≤400 pF to meet rise/fall time requirements (≤300 ns).
Is an external pullup resistor required on the RST pin of DS4510U-15?
Yes, the RST pin of DS4510U-15 is an open-drain output and requires an external pullup resistor to generate a valid high logic level. Maxim recommends a 5.6 kΩ pullup to VCC for typical 5V operation. Without this resistor, RST cannot drive high and system reset functionality will fail. This requirement is explicitly stated in the Pin Description section and confirmed in Typical Operating Characteristics (Figure DS4510 toc05).
