ST92R195B Datasheet | STMicroelectronics

DESCRIPTION 1 GENERAL DESCRIPTION 1.1 INTRODUCTION The ST92R195B microcontroller is developed and manufactured by STMicroelectronics using a proprietary n-well HCMOS process. Its performance derives from the use of a flexible 256-register programming model for ultra-fast context switching and real-time event response. The intelligent onchip peripherals offload the ST9 core from I/O and data management processing tasks allowing critical application tasks to get the maximum use of core resources. The ST92R195B MCU supports low power consumption and low voltage operation for power-efficient and low-cost embedded systems. 1.1.1 ST9+ Core The advanced Core consists of the Central Processing Unit (CPU), the Register File and the Interrupt controller. The general-purpose registers can be used as accumulators, index registers, or address pointers. Adjacent register pairs make up 16-bit registers for addressing or 16-bit processing. Although the ST9 has an 8-bit ALU, the chip handles 16-bit...
