Key Features
- 512 Kbit (64 KB) SRAM capacity with 8-bit wide data bus for byte-level random access in embedded systems
- Up to 20 MHz SPI clock frequency enables fast data transfers in microcontroller-based applications
- Through-hole DIP-8 package (R-PDIP-T8) allows easy breadboard prototyping and hand-soldering for development use
- Separate I/O architecture supports standard SPI, SDI, and SQI modes for versatile bus integration
Applications
The 23LC512-I/P is widely used as an external RAM expansion for microcontrollers such as PIC, AVR, and ARM Cortex-M devices that have limited on-chip SRAM. It is commonly deployed in data logging, audio buffering, display frame buffering, and network packet buffering applications where 64 KB of fast serial memory is needed. The DIP-8 through-hole package makes it especially convenient for prototype and educational designs using breadboards or through-hole PCBs.

Frequently Asked Questions
How much storage does the 23LC512-I/P provide and at what maximum SPI clock rate can it operate?
The 23LC512-I/P provides 512 Kbits (64 KB) of SRAM storage with an 8-bit data width. It supports SPI clock frequencies up to 20 MHz, enabling fast read and write access that complements microcontrollers running at 8 MHz to 48 MHz system clocks typical in PIC and AVR-based designs.
For a data-logging application on a microcontroller with only 2 KB of internal RAM, how does the 23LC512-I/P address the memory gap?
The 23LC512-I/P adds 64 KB of external SRAM over a simple 4-wire SPI interface, expanding available working memory by more than 30 times. At 20 MHz clock, byte-level random access latency is under 1 µs, allowing real-time sensor data buffering before writing to slower flash storage in data-logging firmware.
Why do engineers prefer the DIP-8 package of the 23LC512-I/P for prototyping compared to surface-mount alternatives?
The through-hole DIP-8 package allows direct insertion into standard 0.100-inch pitch breadboards and perf-boards without soldering adapters or hot-air rework tools. For prototyping with microcontroller evaluation boards, the 8-pin through-hole footprint simplifies manual wiring of the 4 SPI lines (SCK, MOSI, MISO, CS) plus VCC, GND, and hold pins during firmware development.
