Analog Devices Inc./Maxim Integrated DS4510U-10+T&R

Overview

DS4510U-10+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 ±10% trip point (4.25V–4.49V), provides adjustable reset timeout (125ms–1000ms), and retains I/O states across power cycles. Used in FPGA bank switching, industrial controls, and PC peripherals for system state persistence and supervised boot.

For engineers reviewing the DS4510U-10+T&R datasheet, DS4510U-10+T&R pinout, DS4510U-10+T&R application, or DS4510U-10+T&R equivalent, key selection criteria include VCC trip accuracy (±10%), I/O retention capability, SEEPROM vs. EEPROM write mode control, open-drain RST output drive strength (10mA sink), and µSOP-10 package compatibility with space-constrained embedded designs.

Technical Context

The DS4510U-10+T&R implements a voltage-monitoring circuit with hysteresis, a programmable reset timer controlled via SEEPROM register F1 (TD1/TD0 bits), and an I²C slave interface compliant with standard- and fast-mode timing. Its RST output is open-drain, requiring external pullup, and asserts low when VCC drops below 4.25V (min) or during software-triggered reset (SWRST bit).

All four I/O pins (I/O0–I/O3) are bidirectional with individually controllable pulldown transistors and selectable internal pullups (4.0–6.5kΩ). Their power-on state is stored in EEPROM and recalled after VCC exceeds 2.0V; during power-down, state is held until VCC falls below 1.9V. Memory includes 64 bytes of user EEPROM (00h–3Fh), 2 bytes of SEEPROM (F2h–F3h), and 6 bytes of SRAM (FAh–FFh).

FAQ

What is the VCC trip point tolerance for DS4510U-10+T&R?

The DS4510U-10+T&R has a ±10% VCC trip point tolerance, meaning it asserts reset when VCC falls below 4.25V (min) and releases reset when VCC rises above 4.49V (max) under nominal 5V operation. This specification is guaranteed across the full -40°C to +85°C temperature range and is factory-trimmed for accuracy without requiring external calibration.

How does the SEEPROM functionality work in DS4510U-10+T&R?

In DS4510U-10+T&R, SEEPROM registers (F2h–F3h, F4h–F7h, F0h, F1h, F9h) behave as volatile SRAM when the SEE bit (Config register F9, bit 4) is set to 1-enabling infinite writes with zero write delay. When SEE = 0, writes persist to EEPROM, retaining values across power cycles. This dual-mode operation lets designers optimize for speed (SRAM mode) or persistence (EEPROM mode) per register group.

Can DS4510U-10+T&R drive LEDs directly?

Yes, DS4510U-10+T&R I/O pins can sink up to 4mA each (VOLIOX ≤ 0.4V at 4mA), sufficient to drive low-current indicator LEDs with appropriate series resistors. The internal pullup (4.0–6.5kΩ) provides a defined high level, but for higher brightness or current, external drivers are recommended. RST pin sinks 10mA and is suitable for driving reset inputs of most MCUs and FPGAs.

What is the maximum I²C bus capacitance supported by DS4510U-10+T&R?

DS4510U-10+T&R supports a maximum total bus capacitance (CB) of 400pF on both SDA and SCL lines, as specified in its AC Electrical Characteristics. This aligns with standard I²C fast-mode requirements. To maintain timing compliance (tR/tF ≤ 300ns), designers must ensure PCB trace capacitance plus device pin capacitance (CI/O = 10pF) and any external components remain within this limit.

Does DS4510U-10+T&R require external pullup resistors on I/O pins?

DS4510U-10+T&R includes selectable internal pullup resistors (4.0–6.5kΩ) for each I/O pin, controlled by the Pullup Enable register (F0h). External pullups are optional and only needed if stronger pullup strength, different resistance value, or bidirectional pullup/pulldown control beyond internal capability is required. The internal pullups eliminate four external resistors in typical I/O expansion use cases.
