ST10R272LT6 16位微控制器TQFP-100封装
16-bit low voltage ROMless MCU with MAC
ST10R272LT6 概述
ST10R272L architecture combines the advantages of both RISC and CISC processors with an advanced peripheral subsystem. The following block diagram overviews the different onchip components and the internal bus structure.
The main core of the CPU contains a 4-stage instruction pipeline, a MAC multiplyaccumulation unit, a separate multiply and divide unit, a bit-mask generator and a barrel shifter. Most instructions can be executed in one machine cycle requiring 40ns at 50MHz CPU clock.
The CPU includes an actual register context consisting of 16 wordwide GPRs physically located in the on-chip RAM area. A Context Pointer (CP) register determines the base address of the active register bank to be accessed by the CPU. The number of register banks is only restricted by the available internal RAM space. For easy parameter p*ing, one register bank may overlap others.
A system stack of up to 1024 bytes is provided as a storage for temporary data. The system stack is allocated in the on-chip RAM area, and it is accessed by the CPU via the stack pointer (SP) register. Two separate SFRs, STKOV and STKUN, are compared against the stack pointer value during each stack access to detect stack overflow or underflow.
