Technical Supplement
20.97 MHz Electrical Characteristics
Devices in the M68HC16 Modular Microcontroller Family are built up from a selection of standard
functional modules. Microcontrollers in the M68HC16 Z Series contain the same central processing
unit (CPU16) and system integration module (SIM), and thus have similar electrical characteristics.
M68HC16 devices that operate at clock frequencies of 20.97 MHz are now available. This publica-
tion contains a new electrical characteristics appendix that supplements the MC68HC16Z1 User's
Manual (MC68HC16Z1UM/AD) and the MC68HC16Z2 User's Manual (MC68HC16Z2UM/AD).
The supplement contains the following updated specifications:
