ZLP12840 OTP MCU
Product Specification
2
The ZLP12840 MCU supports 20 interrupt sources with 6 interrupt vectors, as follows:
2 from T8, T16 time-out and capture
3 from UART Tx, UART Rx, UART BRG
1 from LVD
14 from SMR source P20-P27, P30-P33, P00, P07
Any change of logic from P20-P27, P30-P33 can generate an interrupt or SMR
Additional features include:
IR learning amplifier
Low power consumption11 mW (typical)
Three standby modes:
STOP1.7 A (typical)
HALT0.6 mA (typical)
Low voltage reset
Intelligent counter/timer architecture to automate generation or reception and demod-
ulation of complex waveform and pulsed signals:
One programmable 8-bit counter/timer with two capture registers and two load
registers
One programmable 16-bit counter/timer with one 16-bit capture register pair and
one 16-bit load register pair
Programmable input glitch filter for pulse reception
The UART baud rate generator can be used as another 8-bit timer when the UART
is not in use.
Six priority interrupts
Three external/UART interrupts
Two assigned to counter/timers
One low-voltage detection interrupt
