Appendix A
MC68HLC908JL3E/JK3E/JK1E
A.1 Introduction
This appendix introduces three devices, that are low-voltage versions of MC68HC908JL3E/JK3E/JK1E:
• MC68HLC908JL3E
• MC68HLC908JK3E
• MC68HLC908JK1E
The entire data book apply to these low-voltage devices, with exceptions outlined in this appendix.
A.2 Flash Memory
The Flash memory can be read at minimum V
DD
of 2.2V.
Program or erase operations require a minimum V
DD
of 2.7V.
A.3 Low-Voltage Inhibit
There is no low-voltage inhibit circuit. Therefore, no low-voltage reset. The associated register bits are
reserved bits.
A.4 Oscillator Options
Only crystal oscillator or direct clock input is supported.
A.5 Electrical Specifications
Electrical specifications for low-voltage devices are given in the following tables.
