TEXAS INSTRUMENTS TMS27C020 262144 BY 8-BIT UV ERASABLE TMS27PC020 262144 BY 8-BIT PROGRAMMABLE READ-ONLY MEMORIES handbook

TEXAS INSTRUMENTS TMS27C020 262144 BY 8-BIT UV ERASABLE TMS27PC020 262144 BY 8-BIT PROGRAMMABLE READ-ONLY MEMORIES handbook

Datasheet 16 pages · 198 KB · EN

The document details two types of memory devices: the TMS27C020 series, which are ultraviolet (UV) light erasable electrically programmable read-only memories (EPROMs), and the TMS27PC020 series, which are one-time programmable (OTP) PROMs. Both devices feature a 262144 by 8-bit configuration and utilize power-saving CMOS technology for high-speed operation with simple interfaces to MOS and bipolar circuits.
