STMicroelectronics ST92195

The ST92195C and ST92195D microcontrollers are developed and manufactured by STMicroelectronics using a proprietary n-well HCMOS process. The intelligent on-chip peripherals offload the ST9 core from I/O and data management power consumption of the device can be reduced by more than 95% (Low power WFI). When executing the HALT instruction, and if the Watchdog is not enabled, the CPU and its peripherals stop operating and the status of the machine remains frozen (the clock is also stopped).

GENERAL DESCRIPTION

1.1 INTRODUCTION cy programmable via the CCU. In this mode, the Their performance derives from the use of a flexible 256-register programming model for ultrafast context switching and real-time event response. Halt Mode. A reset is necessary to exit from Halt mode. processing tasks allowing critical application tasks 1.1.3 I/O Ports to get the maximum use of core resources. The ST92195C/D MCU support low power consumption and low voltage operation for power-efficient and low-cost embedded systems. Up to 28 I/O lines are dedicated to digital Input/ Output. These lines are grouped into up to five I/O Ports and can be configured on a bit basis under software control to provide timing, status signals, 1.1.1 ST9+ Core ) The advanced Core consists of the Central t(s Processing Unit (CPU), the Register File and the Interrupt controller. uc The general-purpose registers can be used as acd cumulators, index registers, or address pointers. ro Adjacent register pairs make up 16-bit registers for addressing or 16-bit processing.
