2 Absolute maximum ratings
Stresses beyond these listed in this chapter may cause permanent damage to the device. No
functional operation is implied at or beyond these conditions. Exposure to these conditions for
an extended period may affect the device reliability.
Note:
1) For unprogrammed MTP devices. Blocking bits and software must be rewritten in MTP de-
vices if storage temperature exceedes storage temperature for programmed devices.
These devices are ESD sensitive. Although these devices feature proprietary ESD protection
structures, permanent damage may occur on devices subjected to high energy electrostatic
discharges. Proper ESD precautions have to be taken to avoid performance degradation or
loss of functionality.

3 Electrical Characteristics
All specification are -40C to 85C unless otherwise noted. ROM operates up to 125C.
Note:
1) Power supply: 2.4 V - 5.5 V, temperature is 27C.
2) < 10 erase cycles.
3) More cycles possible during development, with restraint retention
4) With 2 MHz clock, all instructions are using exactly 1 clock cycle
5) Longer erase time may degrade retention
4 CPU
The XE88LC03 CPU is a low power RISC core. It has 16 internal registers for efficient imple-
mentation of the C compiler. Its instruction set is made of 35 generic instructions, all coded on
22 bits, with 8 addressing modes. All instructions are executed in one clock cycle, including
conditional jumps and 8x8 multiplication.
