The DS1558W+TRL is a real-time clock (RTC) module manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features:

Specifications:

• Manufacturer: Maxim Integrated (MAXIM)
• Part Number: DS1558W+TRL
• Type: Real-Time Clock (RTC) with NV SRAM
• Memory Size: 512Kbit (64K x 8) NV SRAM
• Interface: Parallel
• Supply Voltage: 4.5V to 5.5V
• Operating Temperature Range: -40°C to +85°C
• Package: 36-Pin PowerCap Module (PCAP)
• Clock Accuracy: ±2 minutes per month at 25°C
• Battery Backup: Integrated lithium energy source
• Data Retention: Minimum 10 years in the absence of power

Descriptions:

The DS1558W+TRL combines a real-time clock (RTC) with nonvolatile SRAM (NV SRAM) in a single module. It includes an embedded lithium energy source to maintain timekeeping and memory retention when external power is removed. The RTC provides seconds, minutes, hours, day, date, month, and year information, with automatic leap-year compensation.

Features:

• Integrated RTC & NV SRAM: Combines timekeeping with nonvolatile memory.
• Battery Backup: Built-in lithium energy source eliminates the need for an external battery.
• Automatic Leap-Year Compensation: Supports dates up to the year 2100.
• Power-Fail Detection: Monitors VCC and automatically switches to battery backup when power fails.
• Parallel Interface: Easy interfacing with microcontrollers or processors.
• High Reliability: Ensures data retention for at least 10 years without power.
• Industrial Temperature Range: Operates reliably from -40°C to +85°C.
