TinyRISC LR4102 Microprocessor

Note:

there is no setup/hold time requirements for the interrupt

pins, INTP[5:0], because they are synchronized internally

within the LR4102.

Electrical Requirements

This section contains the electrical parameters for the TinyRISC LR4102

Microprocessor in the following tables:

• Table 15 lists the absolute maximum ratings

• Table 16 deﬁnes the recommended operating supply voltage and

temperature

• Table 17 shows the pin capacitance

• Table 18 lists the DC characteristics
