COP8TAB9/TAC9
8-Bit CMOS Flash Microcontroller with 2k Byte or 4k
Byte Memory
1.0 General Description
The COP8TAB9/TAC9 Flash microcontrollers are highly in-
tegrated COP8™ Feature core devices, with 2k or 4k Flash
memory and advanced features. These single-chip CMOS
devices are suited for applications requiring a full featured,
in-system reprogrammable controller with moderate memory
and low EMI. The same device is used for development,
pre-production and volume production with a range of COP8
software and hardware development tools.
A Masked ROM device (COP8TAB5/TAC5) has been devel-
oped and provides identical features except for the Boot
ROM and Flash Memory and related features such as In-
System Programming and reprogrammability. The ROM de-
vice is supported, in emulation, by this device.
The lack of the Boot ROM and Flash Memory in the ROM
device, prompts us to caution the user, utilizing the
COP8TAx9 Flash based devices during development for
applications to be produced using the COP8TAx5 ROM de-
vices, to ensure that code contains NO calls to Boot ROM
functions prior to submission for ROM generation. Instances
of the JSRB instruction in ROM based devices will be ex-
ecuted as a JSR instruction to a location in the first 256 bytes
of Program Memory.
