November 22, 2005
General Description
This device is an 8-bit high performance RISC architec-
ture microcontroller designed for USB product applica-
tions. It is particularly suitable for use in products such
as keyboards and keyboard with calculator. AHALTfea-
ture is included to reduce power consumption. The
mask version HT82K94A is fully pin and functionally
compatible with the OTP version HT82K94E device.
