3.GENERAL DESCRIPTION
The 8032T is a high-performance 8051 family compatible micro-controller based on RISC
architecture & Pipeline design. This IP Specification of interface timing, external Data Memory
read / write timing and external Program Memory read timing are different from that of the standard
80C52. But instruction-set is fully compatible with standard 8051 family.
4.FUNCTIONAL DESCRIPTION
Memory
The R8032TTEX manipulates operands in four memory spaces. There are 64K-byte Program
Memory space, 64K-byte External Data Memory space, 256-byte Internal Data Memory, and with a
16-bit Program Counter space. The Internal Data Memory address space is further divided into the
256-byte Internal Data RAM and 128-byte Special Function Register address space. The up 128-
bytes RAM can reach by indirect addressing. Four Register Banks, 128 addressable bits, and the
stack reside in the Internal Data RAM.
I/O ports
The R8032TTE has 8-bit I/O ports. The four ports and one extra port (Port 4)provide 32 I/O lines to
interface to the external world. All four ports are both byte and bit addressabl but port 4 is only byte
addressable. The R8032TTE uses dedicate bus when external program is running or external
memory/device is accessed. Port 1 is used for both I/O and external interrupts.
Interrupts
In the R8032TTEX there are six hardware resources that generate an interrupt request. The starting
addresses of the interrupt service program for each interrupt source are like standard 8052. The
external interrupt request inputs (
0
INT
,
1
INT
) can be programmed for either negative edge or low
level-activated operation.
3 Timers / Counters
The R8032TTEX has three 16-bit timers/counters that are same as the timers of the standard 8051
family. The R8032TTEX has two additional watchdog timers for system failure monitor.

Serial I/O ports
The R8032TTEX has 2 programmable, full-duplex serial I/O ports that the function is same as that
of 8051 family and dependent on requirement.
Power Management
The R8032TTEX default support IDLE and POWER-DOWN modes of operation. In the IDLE
mode, the CPU core is stopped operation while the peripherals continue operating. In the POWER-
DOWN mode, all the clocks are stopped. The power-down mode can be waked up by
0
INT
or
1
INT
external interrupt with level trigger. The extra power management can be found on PMR
register in SFR.
Dual Data Pointer
The R8032TTEX has 2 data pointers (DTPR, DTPR1). These two data pointers can help users
enhance lots of block data memory moving. Using dual data pointers to move block data almost
saves half of the time spent by original 8051 codes.
Watch Dog Timers Interrupt / Reset
The R8032TTEX creates one programmable watchdog timers to monitor system failure. That is
maximum
26
2 .
Hardware Multiply
R8032TTEX includes a hardware multiplier to enhance calculating speed. R8032TTEX can
finished one multiply instruction at 1 machine cycle.
