This section describes the non-volatile memory (EPROM/OTPROM).
An MCU with a quartz window has 16 Kbytes of erasable, programmable
ROM (EPROM). The quartz window allows EPROM erasure by using
ultraviolet light. In an MCU without the quartz window, the EPROM
cannot be erased and serves as 16 Kbytes of one-time programmable
ROM (OTPROM). An unprogrammed or erased location reads as $00.
The following addresses are user EPROM/OTPROM locations:
Programming tools are available from Freescale. Contact your local
Freescale representative for more information.
A security feature prevents viewing of the EPROM/OTPROM contents.
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or
copying the EPROM/OTPROM difficult for unauthorized users.
