Overview of IC DRAM 512MBIT LVTTL 54TSOP II – 512 Mbit SDRAM, LVTTL, 54‑pin TSOP II
The IC DRAM 512MBIT LVTTL 54TSOP II is a volatile SDRAM device with a memory organization of 128M × 4, providing 512 Mbit of DRAM storage in a 54‑pin TSOP(II) package. It implements an LVTTL interface and is specified for commercial temperature operation.
Key practical characteristics available from the device include a 133 MHz clock frequency (PC133), 65 ns access time, 8K/64 ms refresh, and a 3.0 V to 3.6 V supply range, making it suitable for board‑level DRAM density expansion where these electrical and mechanical specs match system requirements.
Key Features
- Memory Architecture 512 Mbit SDRAM organized as 128M × 4 with 4 banks (device series designation indicates 4‑bank SDRAM).
- Interface LVTTL interface (3.3 V signaling) for standard logic‑level memory interfacing.
- Speed & Timing Clock frequency specified at 133 MHz (PC133) with an access time of 65 ns; ordering code speed grade corresponds to PC133 timing.
- Refresh 8K refresh cycles per 64 ms as indicated in the SDRAM product guide.
- Power Supply voltage range of 3.0 V to 3.6 V consistent with 3.3 V systems.
- Package & Mounting 54‑pin TSOP (0.400", 10.16 mm width) — TSOP(II) package format and listed as lead‑free in the component product guide; surface‑mount device.
- Operating Temperature Commercial temperature range: 0 °C to 70 °C (TA).
Unique Advantages
- Standard LVTTL signaling: Provides direct compatibility with 3.3 V LVTTL memory interfaces as specified by the device.
- PC133 timing support: 133 MHz clock frequency and defined access time (65 ns) enable predictable timing behavior for designs targeting PC133 specifications.
- Compact TSOP(II) package: Delivered in a 54‑pin TSOP(II) footprint (0.400" / 10.16 mm width) for board‑level integration where that package is required.
- Commercial temperature rating: Rated 0 °C to 70 °C for applications operating within standard commercial ambient ranges.
- Defined refresh behavior: 8K/64 ms refresh requirement is specified in the product documentation for system memory maintenance planning.
- Wide supply voltage tolerance: Operates across 3.0 V to 3.6 V, aligning with common 3.3 V memory power rails.
