Description
Input to the on-chip inverting oscillator amplifier
To use the internal oscillator, a crystal/resonator circuit is connected to this pin.
If an external oscillator is used, its output is connected to this pin. X1 is the
clock source for internal timing.
Output of the on-chip inverting oscillator amplifier
To use the internal oscillator, a crystal/resonator circuit is connected to this pin.
If an external oscillator is used, leave X2 unconnected.
PLL Low Pass Filter input
FILT receives the RC network of the PLL low pass filter.

Description
Timer 0 Gate Input
INT0 serves as external run control for timer 0, when selected by GATE0 bit in
TCON register.
External Interrupt 0
INT0 input sets IE0 in the TCON register. If bit IT0 in this register is set, bit IE0
is set by a falling edge on INT0. If bit IT0 is cleared, bit IE0 is set by a low level
on INT0.
Timer 1 Gate Input
INT1 serves as external run control for timer 1, when selected by GATE1 bit in
TCON register.
External Interrupt 1
INT1 input sets IE1 in the TCON register. If bit IT1 in this register is set, bit IE1
is set by a falling edge on INT1. If bit IT1 is cleared, bit IE1 is set by a low level
on INT1.

5. Address Spaces
The AT8xC5132 derivatives implement four different address spaces:
• Program/Code Memory
• Boot Memory
• Data Memory
• Special Function Registers (SFRs)
5.0.1
Code Memory
The AT89C5132 implements 64K Bytes of on-chip program/code memory in Flash technology.
The Flash memory increases ROM functionality by enabling in-circuit electrical erasure and pro-
gramming. Thanks to the internal charge pump, the high voltage needed for programming or
erasing Flash cells is generated on-chip using the standard VDD voltage. Thus, the AT89C5132
can be programmed using only one voltage and allows in application software programming
commonly known as IAP. Hardware programming mode is also available using specific pro-
gramming tools.
5.0.2
Boot Memory
The AT89C5132 implements 4K Bytes of on-chip boot memory provided in Flash technology.
This boot memory is delivered programmed with a standard bootloader software allowing in sys-
tem programming commonly known as ISP. It also contains some Application Programming
Interfaces routines commonly known as API allowing user to develop his own bootloader.
5.0.3
Data Memory
The AT89C5132 derivatives implement 2304 bytes of on-chip data RAM. This memory is divided
in two separate areas:
• 256 bytes of on-chip RAM memory (standard C51 memory).
• 2048 bytes of on-chip expanded RAM memory (ERAM accessible via MOVX instructions).
