CY9A1A0N Series
General-Purpose I/O Port
This series can use its pins as general-purpose I/O ports when
they are not used for peripherals. Moreover, the port relocate
function is built in. It can set which I/O port the peripheral
function can be allocated to.
Capable of pull-up control per pin
Capable of reading pin level directly
Built-in the port relocate function
Up to 84 high-speed general-purpose I/O Ports@100 pin
Package
Some ports are 5 V tolerant I/O
See List of Pin Functions and I/O Circuit Type to confirm the
corresponding pins.
Multi-function Timer
The Multi-function timer is composed of the following blocks.
16-bit free-run timer × 3ch.
Input capture × 4ch.
Output compare × 6ch.
A/D activation compare × 1ch.
Waveform generator × 3ch.
16-bit PPG timer × 3ch.
IGBT mode is contained
The following function can be used to achieve the motor
control.
PWM signal output function
DC chopper waveform output function
Dead time function
Input capture function
A/D convertor activate function
DTIF (Motor emergency stop) interrupt function
HDMI-CEC/Remote Control Receiver (Up to 2
channels)
HDMI- CEC receiver / Remote control receiver
Operating modes supporting the following standards can be
selected
SIRCS
NEC/Association for Electric Home Appliances
HDMI-CEC
Capable of adjusting detection timings for start bit and data
bit
Equipped with noise filter
HDMI-CEC transmitter
Header block automatic transmission by judging Signal free
Generating status interrupt by detecting Arbitration lost
Generating START, EOM, ACK automatically to output CEC
transmission by setting 1 byte data
Generating transmission status interrupt when transmitting 1
block (1 byte data and EOM/ACK)
Real-time clock (RTC)
The Real-time clock can count
Year/Month/Day/Hour/Minute/Second/A day of the week from
00 to 99.
The interrupt function with specifying date and time
(Year/Month/Day/Hour/Minute) is available. This function is
also available by specifying only Year, Month, Day, Hour or
Minute.
Timer interrupt function after set time or each set time.
Capable of rewriting the time with continuing the time count.
Leap year automatic count is available.
External Interrupt Controller Unit
Up to 16 external interrupt input pins
Include one non-maskable interrupt (NMI) input pin
Watchdog Timer (2 channels)
A watchdog timer can generate interrupts or a reset when a
time-out value is reached.
This series consists of two different watchdogs, a Hardware
watchdog and a Software watchdog.
The Hardware watchdog timer is clocked by the built-in
Low-speed CR oscillator. Therefore, the Hardware watchdog is
active in any low-power consumption mode except RTC, Stop,
Deep Standby RTC and Deep Standby Stop modes.
