Applications
The TMS27C210A-10JL is used in legacy embedded processor systems, DSP boards, and industrial controllers that require reliable 16-bit wide non-volatile code or data storage. Its ceramic DIP package and UV-erasable cells make it a preferred choice in aerospace, military, and scientific instruments where long storage life, radiation tolerance, and field reprogrammability are valuable. Engineers also use this device for prototype firmware development and small-volume production runs where mask-ROM turnaround time is not acceptable.

Frequently Asked Questions
What is the memory capacity and organization of the TMS27C210A-10JL, and how does it interface with 16-bit processors?
The TMS27C210A-10JL is organized as 65,536 words × 16 bits, totaling 1,048,576 bits (1 Mb) of EPROM storage. The 16-bit wide data bus allows direct connection to 16-bit microprocessors and DSPs such as the TMS320 family without external data-width conversion logic, simplifying PCB layout and reducing read cycle overhead.
How fast can the TMS27C210A-10JL deliver data, and what bus speeds does a 100 ns access time support?
With a 100 ns maximum access time, the TMS27C210A-10JL can supply valid data within one bus cycle of processors running at up to approximately 10 MHz without wait states, or at higher clock rates with one or two programmed wait states. This speed grade is designated by the '-10' suffix and is appropriate for 8 MHz to 12 MHz legacy embedded controller designs.
Why is a ceramic side-brazed DIP package preferred for the TMS27C210A-10JL in industrial and military designs?
The ceramic side-brazed package offers hermetic sealing and a moisture resistance level far superior to plastic DIP, enabling the TMS27C210A-10JL to survive harsh environments with temperature cycling from -55 °C to +125 °C and humidity exposure that would degrade plastic-package EPROMs. Military and aerospace applications often mandate ceramic packaging under MIL-STD-883 to ensure long-term data retention in storage and field use.
How many erase-reprogram cycles does UV EPROM technology typically support, and what UV exposure time is needed?
UVPROM technology like that used in the TMS27C210A-10JL typically guarantees at least 100 erase-reprogram cycles before cell endurance degrades. UV erasure at 253.7 nm wavelength with an intensity of 12 mW/cm² requires approximately 15 to 20 minutes of exposure through the quartz window, after which the device can be reprogrammed at 12.5 V VPP for a new firmware revision.
