K4S510432D-UC75

The K4S510432D-UC75 is a 512 Mbit SDRAM device organized as 128M × 4 with an LVTTL interface, supplied in a 54‑pin TSOP II package. It is designed for commercial‑temperature applications and targets systems requiring standard 3.3 V SDRAM memory with PC133 timing.

This component is suitable for embedded and electronic designs that need synchronous DRAM memory with a 133 MHz clockability, a default CAS latency configuration, and a compact 54‑TSOP footprint for board‑level integration.

Key Features

• Memory Core SDRAM volatile memory, 512 Mbit capacity organized as 128M × 4 with 4 banks as specified for the 512Mb D‑die family.
• Performance & Timing PC133 class operation with a clock frequency rating of 133 MHz and default CAS latency (CL=3). Access time specified at 65 ns.
• Interface & Power LVTTL memory interface with supply voltage range 3.0 V to 3.6 V (noted as 3.3 ± 0.3 V in device documentation).
• Refresh & Organization 8K refresh cycle per 64 ms as indicated for the 512 Mbit D‑die devices; organized for synchronous burst operation typical of SDRAMs.
• Package 54‑pin TSOP (TSOP II) package, 0.400" (10.16 mm) width, suitable for compact board layouts.
• Temperature Range Commercial operating temperature range of 0°C to 70°C (TA).

Typical Applications

• Embedded Systems Used as system DRAM where a compact 54‑pin package and LVTTL interface are required for memory expansion or buffering.
• Consumer Electronics Suitable for commercial‑temperature consumer designs that implement PC133‑class SDRAM for data buffering and working memory.
• Industrial Control Applicable where 3.3 V SDRAM is needed within the 0°C to 70°C operating range for control and monitoring functions.

Unique Advantages

• Standard LVTTL Interface: Simplifies integration with systems designed for 3.3 V LVTTL memory signaling.
• PC133 Timing Compatibility: 133 MHz clock rating and default CL=3 timing make the device compatible with PC133‑class SDRAM timing domains.
• Compact TSOP II Package: 54‑pin TSOP II footprint helps reduce board area while providing full SDRAM functionality.
• Commercial Temperature Operation: 0°C to 70°C rating aligns with typical commercial application requirements.
• Documented Refresh and Bank Architecture: 8K/64 ms refresh and 4‑bank organization provide predictable memory management for system designers.
