MC68HC908EY8
A.1 Introduction
The MC68HC908EY8 is a member of the low-cost, high-performance M68HC08 Family of 8-bit
microcontroller units (MCUs). All MCUs in the family use the enhanced M68HC08 central processor unit
(CPU08) and are available with a variety of modules, memory sizes and types, and package types.
The information contained in this document pertains to the MC68HC908EY8 with the exceptions shown
in this appendix.

A.3 Memory
The memory map, shown in
The FLASH memory is an array of 7680 bytes with an additional 36 bytes of user vectors and one byte
used for block protection. The FLASH is organized internally as an 8192-word by 8-bit complementary
metal-oxide semiconductor (CMOS) page erase, byte (8-bit) program embedded FLASH memory. Each
page consists of 64 bytes. The page erase operation erases all words within a page. A page is composed
of two adjacent rows.
A security feature prevents viewing of the FLASH contents.
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or copying the FLASH difficult for
Freescale Semiconductor
unauthorized users.
