Frequently Asked Questions
What are the memory density and organization of the M27C512-10C6?
The M27C512-10C6 provides 512Kbits of OTP ROM organized as 65,536 words by 8 bits each, totaling 64KB of addressable program or data storage. This capacity suits firmware images and look-up tables in 8-bit microprocessor-based embedded systems running from a 5 V supply rail.
How fast can the M27C512-10C6 respond to a memory read cycle in a legacy bus design?
The M27C512-10C6 has a maximum access time of 100 ns, making it compatible with 8 MHz or faster legacy CPU buses. This speed spec ensures reliable read operations without wait states on common Z80, 8051, or 68000-family processor designs operating at standard clock rates.
Which package does the M27C512-10C6 come in and how does it compare to DIP versions?
The M27C512-10C6 ships in a 32-pin PLCC (Plastic Leaded Chip Carrier) package, offering a smaller PCB footprint than a 28-pin DIP variant while maintaining JEDEC-standard pinout compatibility. The surface-mount profile is advantageous for compact board designs that still need through-hole socket flexibility via PLCC sockets.
In what embedded scenarios is the M27C512-10C6 preferred over Flash memory?
The M27C512-10C6 is preferred in safety-critical or tamper-resistant designs where OTP (One-Time Programmable) memory guarantees that firmware cannot be altered in the field. Applications such as industrial calibration constants, medical device firmware, and automotive ECU code benefit from the permanent 64KB storage and 100 ns read access with a simple 5 V supply.
