1.1.2 XE88LC01 vs XE88LC01A
The XE88LC01A has a new RESET pin function. The action of the RESET pin of the XE88LC01A
resets the clock registers too and creates an additional short delay. See the RESET chapter for more
information.

2.3.1
Flash circuit
The flash version of the circuit can be run from a supply between 2.4V and 5.5V (Figure 2-1). The
capacitor on VREG has to be connected at all times (value in Table 2-2) to guarantee proper
operation of the device. The capacitor on VMULT is only required if the circuit is to be operated below
3V.

2.3.2
ROM circuit
For the ROM version, two possible operating modes exist: with and without voltage regulator. Using
the voltage regulator, low power consumption will be obtained even with supply voltages above 2.4V.
Without the voltage regulator (i.e. VREG short-circuited to VBAT), a higher speed can be obtained.
2.1.3.1 Low power operation
In this case, the internal voltage regulator is used in order to maintain a low power consumption
independent from the supply voltage. The capacitor on VREG has to be connected at all times (value
in Table 2-3) to guarantee proper operation of the device. The capacitor on VMULT has to be
connected only when VBAT<3V.
