CY9AA30N 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 5V 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 × 3 ch.
Input capture × 4 ch.
Output compare × 6 ch.
A/D activating compare × 3 ch.
Waveform generator × 3 ch.
16-bit PPG timer × 3 ch.
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

Document Number: 002-05640 Rev. *C
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.
Clock and Reset
[Clocks]
Selectable from five clock sources (2 external oscillators, 2
built-in CR oscillators, and Main PLL).
Main Clock:
4 MHz to 20 MHz
Sub Clock:
32.768 kHz
Built-in High-speed CR Clock: 4 MHz
Built-in Low-speed CR Clock: 100 kHz
Main PLL Clock
[Resets]
Reset requests from INITX pin
Power-on reset
Software reset
Watchdog timers reset
Low-voltage detection reset
Clock Super Visor reset
Clock Super Visor (CSV)
Clocks generated by built-in CR oscillators are used to
supervise abnormality of the external clocks.
If external clock failure (clock stop) is detected, reset is
asserted.
If external frequency anomaly is detected, interrupt or reset is
asserted.
