Built on a 1.2 V core, 65 nm flash process, the device combines up to 5,120 Kbits of embedded SRAM, 240 Math Blocks (18x18 multipliers), 4 PLLs and DLLs, and 1.2 Gbps SERDES capability, addressing low-density logic integration and high-speed serial bridging without an external MCU. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected by programmable interconnect, allowing designers to customize digital functions after fabrication. FPGAs sit in the hierarchy: programmable logic -> logic IC -> integrated circuit -> semiconductor. The IGLOO2 family specifically targets low-power operation with flash-based configuration cells that retain bitstream in silicon without external boot memory, simplifying board design and improving security. Key features include 512 Kbits of embedded non-volatile memory (eNVM), 64 KB embedded SRAM (eSRAM), high-performance DDR2/DDR3/LPDDR memory controller interfaces with ECC, integrated DSP through the Math Block array, and an ARM Cortex-M3 hard processor subsystem variant (M2GL150S). The I/O count of 248 supports wide parallel interfaces for video bridging, industrial control and communications aggregation. The flash-based architecture provides instant-on capability and inherent security against bitstream read-back, advantages over SRAM-based FPGAs that require external boot PROMs. From a technical depth perspective, the M2GL150 uses a 4-input LUT fabric with dedicated carry chains and distributed control logic, providing a fine-grained architecture suitable for glue logic, bus bridging and signal conditioning. The 65 nm low-power process node enables sub-microamp sleep currents and flexible power modes that suit battery-powered and industrial always-on applications. Typical applications include industrial control planes, secure communications bridges, motor control and I/O expansion, video/image processing, and low-power system management. The flash-based non-volatile configuration makes the device particularly attractive for safety-critical and secure systems requiring deterministic boot and tamper resistance. When designing, ensure the PCB layout accommodates the 484-ball FBGA 19x19 mm land pattern with controlled-impedance traces for SERDES lanes and matched-length DDR routing for memory interfaces. Heat dissipation is generally low due to flash-based operation, but core utilization above 70 percent may require thermal analysis.

M321R4GA0PB2-CCP - 32GB DDR5-6400 ECC RDIMM | Samsung

The Samsung M321R4GA0PB2-CCP is a 32GB DDR5-6400 ECC registered DIMM (RDIMM) operating at 6400 MT/s (PC5-51200) on a 1.1V supply, packaged as a 288-pin DIMM in a 1Rx4 single-rank x4 configuration. A registered DIMM (RDIMM) is a server memory module that buffers the address and command signals through a register chip before they reach the DRAM devices. This buffering reduces the electrical load on the memory controller, enabling higher module counts per channel and greater total capacity in servers and workstations. RDIMMs sit within the DDR5 SDRAM module hierarchy: DRAM device -> FBGA-packaged die -> registered DIMM -> memory subsystem, and they differ from LRDIMMs (which buffer data as well) and UDIMMs (which have no buffering). Key features of the M321R4GA0PB2-CCP include 32GB capacity organized as 4G x 72 (including 8 bits of ECC per 64-bit word), DDR5-6400 operation at CL52 latency, on-die ECC plus side-band ECC checking, and 1.1V operation aligned with the JEDEC DDR5 standard for reduced power per bit versus DDR4. The module uses twenty 4G x 4 DDR5 DRAM devices in FBGA packages, giving a single-rank x4 topology that the memory controller addresses as one rank. Technically, DDR5 moves the power management from the motherboard to an on-module PMIC (12V to 1.1V conversion), improving signal integrity and power efficiency. Dual 32-bit sub-channels per module improve effective bandwidth and reduce contention. The -CCP speed bin denotes the 6400 MT/s grade, delivering 51.2 GB/s peak bandwidth per channel pair. Typical applications include enterprise servers, edge compute nodes, low virtual-machine-density hosts, workstations, and general-purpose data center platforms from Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, and Supermicro using Intel Xeon or AMD EPYC processors with DDR5 memory controllers. A key design consideration: RDIMMs must only be mixed with other RDIMMs of the same generation on a channel; they cannot be combined with UDIMMs or LRDIMMs, and maximum supported speed depends on the CPU memory controller and populated channel configuration.

The Samsung M321R4GA3EB0-CWM is a 32GB DDR5-5600 ECC Registered DIMM (RDIMM) operating at 1.1V with CL46 latency, housed in a 288-pin DIMM form factor. This dual-rank x8 (2Rx8) module delivers PC5-44800 bandwidth and is organized as 4Gx72 with twenty FBGA-packaged 2Gx8 DDR5 DRAM devices plus a registering clock driver for server-grade reliability. A Registered DIMM (RDIMM) is a server memory module that buffers address and command signals through a registering clock driver (RCD), reducing electrical load on the memory controller and enabling higher capacities and densities than unbuffered UDIMMs. RDIMMs sit within the DDR5 SDRAM family, which itself belongs to the broader category of volatile DRAM memory used in servers, workstations, and enterprise storage. ECC (Error Correcting Code) functionality detects and corrects single-bit memory errors, which is essential for data integrity in 24/7 datacenter operation. Key features include DDR5-5600 data rate (PC5-44800), 32GB capacity in a dual-rank configuration that balances density and signal integrity, 1.1V operation that lowers power draw versus DDR4's 1.2V, and on-module ECC registered architecture. DDR5's on-die ECC, bank grouping, and dual 32-bit subchannels per DIMM improve effective bandwidth and reliability at speed. Technically, the module uses 20 pieces of 2Gx8 FBGA DDR5 DRAM across two ranks, with a registering clock driver managing command/address traffic. The x72-wide data path (64-bit data plus 8 bits of ECC-style check bandwidth) supports the RDIMM error-handling architecture. Typical applications include Dell PowerEdge C6620, MX760c, R660, and R660xs servers (OEM cross-reference Dell P8XPW), edge compute nodes, low-VM-density hosts, and general-purpose virtualization platforms that list DDR5-5600 RDIMMs on their qualified vendor list. Design consideration: always verify module presence against the server platform's Qualified Vendor List (QVL), since RDIMM speed may train down if the platform only supports lower DDR5 rates.

M321R8GA0EB2-CWM - 64GB DDR5-5600 ECC RDIMM | Samsung

The Samsung M321R8GA0EB2-CWM is a 64GB DDR5-5600 ECC registered DIMM (RDIMM) with dual-rank x4 (2Rx4) organization, operating at 1.1V on a 288-pin DIMM module built with Samsung D-die DRAM devices in a (4G x 4) x 40 composition. Registered (buffered) DIMMs are a class of server memory modules in which address, command, and control signals pass through a register chip before reaching the DRAM devices. This buffering reduces the electrical load on the memory controller, allowing servers and workstations to populate more DIMM slots per channel than is possible with unbuffered (UDIMM) memory. RDIMMs sit within the memory module hierarchy: DDR5 SDRAM device -> registered DIMM -> server memory -> enterprise datacenter memory subsystem. On-die ECC plus registered operation makes them mandatory in most multi-socket x86 server platforms. Key features of the M321R8GA0EB2-CWM include 5600 MT/s data rate (2800 MHz clock, PC5-44800 bandwidth class), CAS latency of CL46 at the rated speed, dual-rank x4 organization that improves server memory capacity scaling, and 1.1V operation that lowers power draw versus DDR4 RDIMMs running at 1.2V. The DDR5 architecture also moves the power management IC (PMIC) onto the module and introduces two independent 32-bit subchannels per module, improving memory bandwidth efficiency for multi-core CPUs. Technically, the module uses Samsung D-die 4G x 4 DDR5 DRAM components, 40 of which compose the 64GB (8G x 72 including ECC bits) registered module. The x4 device width combined with registered operation supports strong RAS (reliability, availability, serviceability) characteristics demanded in virtualization and database environments. On-die ECC detects and corrects single-bit errors internal to each DRAM die, while the registered interface maintains signal integrity at high slot counts. Typical applications include Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, and Supermicro server platforms, as well as virtualization hosts, in-memory databases, and AI inference servers requiring high-capacity registered memory. Multiple identical modules should be installed in matched sets for optimal multi-channel bandwidth. When designing or upgrading, confirm platform BIOS support for DDR5-5600 RDIMMs, as many platforms default to lower speeds such as 4800 MT/s or 5200 MT/s depending on populated DIMMs per channel. Mixing module speeds causes all modules to run at the slowest common speed.

M41T65Q6F - Serial RTC with Alarm, I2C, 1.3V-3.6V | STMicroelectronics

The STMicroelectronics M41T65Q6F is a serial access real-time clock (RTC) integrated circuit with alarm functions, providing a complete Clock/Calendar function plus 32.768 kHz output in a 16-pin VQFN exposed-pad package. The device communicates through a 400 kHz I2C (2-wire serial) interface, operates from 1.3 V to 3.6 V supply, and integrates memory-mapped registers for seconds, minutes, hours, day, date, month, year, and century tracking with automatic leap-year compensation through the year 2100. A Real-Time Clock (RTC) is a category of low-power timing IC that maintains accurate wall-clock time and date information independent of the system microcontroller. RTCs are essential components in any battery-backed system that must preserve time-of-day across power cycles. The M41T65 belongs to the RTC IC > Clock/Calendar > I2C RTC sub-family, and within ST's product hierarchy it sits under Timekeeping ICs > Serial RTC > RTC with Alarms. RTCs bridge the gap between digital logic and physical time by using a 32.768 kHz crystal oscillator as the time-base reference and counting oscillator cycles to derive seconds, minutes, hours, and calendar days. Key features of the M41T65Q6F include a wide operating voltage range of 1.3 V to 3.6 V (suitable for direct battery backup operation), integrated alarm and interrupt functions, a programmable square-wave output derived from the 32.768 kHz crystal, low power consumption typically below 1 microamp in battery backup mode, and an automatic backup switchover when VCC falls below a defined threshold. The 16-pin VQFN-EP (QFN-16) exposed-pad package provides low thermal resistance for stable operation across the -40 °C to +85 °C industrial temperature range and supports automated PCB assembly. Architecturally, the M41T65Q6F combines a 32.768 kHz crystal oscillator, frequency divider chain, BCD-coded time/date registers, I2C interface logic, alarm comparators, and a trickle charger circuit. The internal oscillator drives a divider that produces 1-second resolution. Time and date are stored in Binary-Coded Decimal (BCD) format for direct display compatibility. The integrated trickle charger allows the device to recharge an external backup supercapacitor or rechargeable battery when main power is present, then automatically switch over to backup supply on VCC failure. Typical applications include metering and data-logging systems, industrial controllers requiring time-stamped events, point-of-sale (POS) terminals, medical devices needing scheduled dosing or data recording, consumer electronics with calendar/alarm functions, and any battery-backed embedded system that needs to wake the host MCU at scheduled times. The low 1.3 V minimum supply also makes the M41T65Q6F well-suited for single-cell battery systems. When designing with the M41T65Q6F, ensure the 32.768 kHz crystal load capacitance matches the datasheet specification (typically 12.5 pF) and place the crystal traces as short and symmetric as possible to minimize parasitic capacitance. A decoupling capacitor of 0.1 microfarad should be placed within 2 mm of the VCC pin. The exposed pad (EP) must be soldered to the ground plane for mechanical and thermal reliability.

M41T81SM6F - Serial RTC 2.7-5.5V I2C 8-SOIC | STMicroelectronics

The STMicroelectronics M41T81SM6F is a low-power serial real-time clock (RTC) with a built-in 32.768 kHz external-crystal-controlled oscillator, supplied in an 8-pin SOIC (SO-8) surface-mount package. It operates from 2.7 V to 5.5 V, communicates over a 400 kHz I2C (2-wire) serial interface, and provides a 64-byte BCD-formatted clock/calendar register map covering tenths/hundredths of seconds through century. A Real-Time Clock (RTC) is a dedicated integrated circuit that keeps track of wall-clock time even when the main system is powered down. RTCs sit at the bottom of the timekeeping hierarchy: RTC -> clock/calendar IC -> clock and timing -> semiconductor. They are essential wherever a system must maintain accurate time/date stamping across power cycles, such as data loggers, metering equipment, and industrial controllers. The M41T81S is one of the few RTCs that integrates both the 32.768 kHz crystal interface and the compensation circuitry in a single 8-pin package, reducing BOM and board area. Key features include 2.7 V to 5.5 V single-supply operation, low typical current consumption for battery-backed operation, programmable alarm and watchdog functions, automatic leap-year compensation through year 2099, and a software clock calibration function that can compensate crystal aging in 5 ppm steps. The I2C slave address is fixed at 0x68 with the A0 pin grounded. Internally, the M41T81S combines an external 32.768 kHz crystal oscillator circuit with a binary-coded decimal (BCD) counter chain. Eight bytes of on-chip SRAM back the clock/calendar registers and are accessed via the standard I2C protocol. The device supports both 100 kHz Standard-mode and 400 kHz Fast-mode I2C, making it compatible with most microcontroller families. The byte-wide register map follows the ST M41Txx family convention for drop-in software portability. Typical applications include industrial automation controllers, point-of-sale terminals, metering (electricity/water/gas), data loggers, medical devices requiring timestamped events, automotive telematics and infotainment subsystems, security and access-control panels, and any battery-backed embedded system needing persistent wall-clock time. When designing with the M41T81SM6F, place the 32.768 kHz crystal within 5 mm of the OSCIN/OSCOUT pins and guard those traces with a ground ring to minimize stray capacitance. Provide a backup battery (typically a 3 V coin cell) on VCC with a series Schottky or Schottky-plus-resistor OR-ing network so the RTC domain remains powered during main-rail outages. Use 100 nF decoupling close to VCC and observe the I2C pull-up sizing rules for the chosen bus speed. This page consolidates distributor pricing, parametric drop-in alternatives, and practical layout notes that complement the manufacturer datasheet, giving engineers a single reference for sourcing and designing in the M41T81SM6F.

M41T82RM6F - Low-Power I2C RTC with 32.768 kHz | STMicroelectronics

The STMicroelectronics M41T82RM6F is a low-power serial I2C real-time clock and calendar with a built-in 32.768 kHz oscillator, a 7-bit register address format, and an 8-pin SOIC package measuring 3.90 mm wide. It operates from a 2.0 V to 5.5 V clock supply range and provides battery-backed timekeeping with an ultra-low battery supply current of 365 nA. The device is designed for systems that require accurate calendar time, programmable alarms, periodic events, and low standby power. A real-time clock is a specialized timekeeping integrated circuit that maintains seconds, minutes, hours, date, day, month, and year information even when the main system is unpowered. The RTC category sits within clock and timing semiconductors, where crystal-based oscillators, dividers, registers, and digital interfaces work together to provide a stable time reference. Unlike a software timer, an RTC can continue counting through power loss and can be read again when the host processor restarts. The M41T82RM6F combines an external-crystal-controlled oscillator architecture with low-power serial communication. Its programmable alarm and timer functions can wake a connected microcontroller or signal that a scheduled interval has elapsed. The I2C interface reduces wiring requirements in compact embedded systems, while the 2.0 V to 5.5 V operating range supports both low-voltage and conventional supply environments. The 365 nA battery supply current is especially relevant for battery-backed meters, industrial recorders, and portable instruments. The STMicroelectronics M41T82 family description identifies the SO8 version as using an external 32.768 kHz crystal. Accurate timekeeping therefore depends not only on the RTC electronics but also on crystal selection, load-capacitance matching, layout quality, and temperature behavior. The M41T82RM6F is suited to data loggers, access-control terminals, metering equipment, industrial controllers, and consumer products requiring persistent timestamps. Its low standby consumption helps reduce energy use when the main supply is absent. For a robust design, place the RTC and its crystal close together on the PCB, keep high-current switching paths away from the oscillator network, and provide the required bypass capacitance. Confirm the exact pin functions, register behavior, alarm polarity, and electrical limits against the manufacturer datasheet before layout release. The verified source data supports the component identity, package, interface, oscillator, supply range, and low-current claims; additional operating details remain subject to the full STMicroelectronics datasheet. This page combines verified manufacturer and distributor information with application guidance, comparison fields, and design notes. It is intended to help engineers identify whether the M41T82RM6F fits a low-power battery-backed timekeeping design while distinguishing verified facts from parameters requiring confirmation from the latest datasheet.

M41T94MQ6F - Serial RTC 44B NVRAM SPI 16-SOIC | STMicroelectronics

The STMicroelectronics M41T94MQ6F is a serial real-time clock (RTC) with 44 bytes of NVRAM and a RESET output, packaged in a 16-pin SOIC (0.154", 3.90 mm width). It provides a complete clock/calendar function with tenths/hundredths of seconds, seconds, minutes, hours, day, date, month, year, and century counters, and communicates with the host MCU through a 4-wire SPI bus at clock rates up to 2 MHz. The internal 32,768 Hz oscillator integrates 12.5 pF of load capacitance, allowing direct connection of an external tuning fork crystal without external load capacitors while still tolerating high crystal series resistance (up to 80 kΩ typical). A real-time clock (RTC) is a low-power integrated circuit that maintains accurate wall-clock time using a quartz crystal reference, even when the main system is powered down. RTCs sit within the broader hierarchy of clock-and-timing ICs, which include general-purpose timers, oscillators, and PLL/clock generators. Unlike MCU-internal time counters, dedicated RTC ICs add battery backup switchover, calendar logic, and non-volatile user memory that survives both system reset and loss of main supply. Key features of the M41T94MQ6F include SPI serial interface, 44 bytes of battery-backed NVRAM (16 bytes general-purpose plus 8 bytes used by the clock/calendar), a RESET output pin that asserts a fixed-duration low pulse for system brown-out management, and an integrated 32 kHz oscillator with on-chip load capacitance. The device operates from 2.7 V to 5.5 V main supply and is specified for the industrial -40 °C to +85 °C temperature range. Typical applications include metering (electricity/water/gas), point-of-sale terminals, data loggers, industrial controllers, and any embedded system that needs a tamper-resistant, battery-backed time stamp separate from the application MCU. Designers should add a lithium backup cell (or supercapacitor) to the VBAT pin and follow the crystal-layout guidance in the ST datasheet for long-term timekeeping accuracy.

M471A2G43AB2-CWE - 16GB DDR4-3200 SO-DIMM | Samsung

The Samsung M471A2G43AB2-CWE is a 16 GB unbuffered non-ECC DDR4 SO-DIMM module rated at 3200 MT/s (PC4-25600), organised as a single 1x16 GB rank in the industry-standard 260-pin SO-DIMM form factor used in laptops, mini-PCs, and small-form-factor systems. A SO-DIMM (Small Outline Dual In-Memory Module) is a compact JEDEC-standard memory module derived from the full-size DIMM but roughly half the height. DDR4 SDRAM is the fourth generation of double data rate synchronous DRAM; it operates at lower voltage (1.2 V) than DDR3 (1.5 V), reaches higher per-pin data rates up to 3200 MT/s at launch, and uses a 288/260-pin edge connector with point-to-point topology. The SO-DIMM variant mounts vertically in laptop sockets and supports up to 2 ranks per module (2DPC in some platforms). Key features include 16 GB density in a 1Rx8 organisation (built from sixteen 1 Gx8 FBGA-78 die), 3200 MT/s transfer rate (PC4-25600), CAS Latency 22 (CL22), 1.2 V typical operating voltage (1.14-1.26 V per JEDEC DDR4 spec), and JEDEC-compliant 260-pin SO-DIMM edge finger geometry. The module is unbuffered, non-ECC, and supports standard SPD timings for plug-and-play compatibility with Intel and AMD mobile platforms. Technically, the module follows the JEDEC DDR4 standard JESD79-4, supporting on-die termination (ODT), command/address parity on qualified platforms, and write CRC for signal-integrity robustness. The 1Rx8 organisation routes a single 64-bit data word through eight x8 DRAM devices per rank, balancing density and signal loading for mobile workloads. Typical applications include laptop memory upgrades, ultrabook and thin-client RAM expansion, mini-PC and small-form-factor workstations, and embedded industrial PCs that require JEDEC-standard SO-DIMM compatibility. The 3200 MT/s rating aligns with mainstream 11th/12th-generation Intel Core and AMD Ryzen mobile platforms. Design consideration: when populating two SO-DIMM sockets, mixing 1Rx8 and 2Rx8 modules downgrades the channel to the slower rank's timings on some chipsets - use matched modules for dual-channel performance.

M48T02-70PC1 - 5V 16Kbit TimeKeeper SRAM RTC | STMicroelectronics

The STMicroelectronics M48T02-70PC1 is a 5.0 V, 16 Kbit (2 Kb x 8) non-volatile TimeKeeper SRAM that integrates an ultra-low-power SRAM, a real-time clock (RTC), and a power-fail control circuit in a single 24-pin DIP Module package (0.600 inch / 15.24 mm). The device is pin and function compatible with the JEDEC-standard 2 Kb x 8 SRAM footprint, allowing direct replacement of a parallel SRAM while adding battery-backed timekeeping. Access time is 70 ns, matching common asynchronous SRAM timing requirements. The on-board lithium coin cell provides a minimum of 10 years of data and clock retention in the absence of external power across the operating temperature range. A real-time clock (RTC) is a dedicated integrated circuit that tracks seconds, minutes, hours, days, dates, months, and years with automatic leap-year compensation. The M48T02 family combines RTC functionality with a non-volatile static RAM, forming a TIMEKEEPER (utility) hybrid module that retains data and time without external backup hardware. Such modules sit in the system hierarchy as Memory ICs > Non-volatile SRAM > RTC + SRAM combination modules, and are widely used when a host MCU needs both configuration storage and wall-clock time across power cycles. Key features include a parallel address/data bus interface (multiplexed to match a standard 2K x 8 SRAM pinout), BCD-formatted clock registers, automatic leap-year correction through 2099, programmable square-wave output, and built-in power-fail write protection that locks the SRAM when VCC drops below the lithium backup threshold. The TIMEKEEPER (utility) architecture means the user simply reads and writes the SRAM address space - clock information is mapped into the upper RAM addresses - so existing SRAM software drivers work with no modification. Typical applications include industrial controllers, point-of-sale terminals, data loggers, metering equipment, security and access-control systems, and any embedded design that needs both battery-backed parameter memory and a calendar-clock. Designers should observe the VCC power-up ramp specifications in the datasheet to ensure the battery switchover circuit latches correctly, and avoid applying external bias to the backup cell. The through-hole DIP-24 module remains popular for legacy boards, prototypes, and field-replaceable designs where socketed parts are desirable.

M48T58-70PC1 - 64Kbit Timekeeper SRAM RTC 70ns | STMicroelectronics

The STMicroelectronics M48T58-70PC1 is a 5.0 V, 64 Kbit (8 Kb x 8) non-volatile Timekeeper SRAM that integrates an 8 Kb x 8 static RAM, a real-time clock, a power-fail control circuit, and a lithium battery in a single 28-pin DIP Module package. It provides 70 ns access time and operates over a 4.75 V to 5.5 V supply range, delivering a battery-backed-up memory and real-time clock solution in one footprint. A Timekeeper SRAM is a hybrid non-volatile memory device that combines the byte-wide random access of a standard SRAM with on-chip battery backup and an integrated real-time clock. It belongs to the broader family of non-volatile RAM (NVRAM) products, sitting between conventional SRAM and serial NVSRAM/FRAM in the memory hierarchy. Compared to standard SRAM, a Timekeeper eliminates external battery-management circuitry and supports BCD-coded year/month/day/date/hour/minute/second read-out. Key features include 70 ns read/write access time, integrated lithium battery with typical 10-year data retention, automatic power-fail/write-protection circuitry, bytewide RAM-like clock access, BCD-coded year/month/day/date/hour/minute/seconds registers, frequency test output for real-time clock, and JEDEC-standard 8 K x 8 SRAM pin/function equivalence. The monolithic chip ships in a special 28-pin DIP Module (CAPHAT) that accommodates the embedded battery cell. The architecture centers on a low-power 8K x 8 SRAM array, a 32 kHz crystal-controlled oscillator for the RTC, and a power-fail comparator that latches the CS/WE/OE write-protect signals when VCC drops below a defined threshold. The internal lithium cell then holds both the SRAM contents and the RTC registers, allowing the device to drop into any JEDEC-standard 8K x 8 SRAM socket without any WRITE-timing constraints. Typical applications include industrial data logging, point-of-sale terminals, metering equipment, factory automation controllers, medical instruments, and any embedded system that requires both non-volatile variables and a wall-clock/calendar without an external backup battery or RTC chip. Designers use it as a one-chip substitute for SRAM + discrete RTC + supercapacitor/cell combinations. When designing with this device, observe the standard 8K x 8 SRAM timing (address setup, CS-to-OE, write-pulse width) and route the VCC decoupling close to the supply pin. Because the lithium cell is non-replaceable in the CAPHAT package, treat the module as a sealed unit; planned end-of-life data retention after VCC removal is on the order of 10 years per the manufacturer. This page synthesizes distributor pricing, verified drop-in alternatives, and practical design notes that go beyond the manufacturer's datasheet, supporting faster component evaluation.
