4.2 Introduction
The MMC2107 is available in two packages:
• 100-pin Joint-Electron Device Engineering Council (JEDEC)
low-profile quad flat pack (LQFP) — The 100-pin device is a
minimum pin set for single-chip mode implementation.
• 144-pin JEDEC LQFP — The 144-pin implementation includes 44
optional pins as a bond-out option to:
– Accommodate an expanded set of features
– Allow expansion of the number of general-purpose
input/output (I/O)
– Utilize off-chip memory
– Provide enhanced support for development purposes
The optional group of pins includes:
• 23 address output lines
• Four chip selects
• Two emulation chip selects
• Four byte/write enables
• Read/write (R/W) signal
• Output enable signal
• Three transfer code signals
