GENERAL DESCRIPTION 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. ■ Register File based 8/16 bit Core Architecture with RUN, WFI, SLOW and HALT modes ■ 0°C to +70°C Operating Temperature Range available ■ Up to 24 MHz Operation @ 5V±10% ■ Minimum instruction cycle time: 375ns at 16 MHz internal clock ■ 4 Mbytes address space ■ 256 Bytes RAM of Register file (accumulators or index registers) ■ 1024 Bytes of on-chip static RAM ■ 8K Bytes of TDSRAM (Teletext and Display Storage RAM) ■ 80-lead QFP package ■ 23 fully programmable I/O pins ■ Serial Peripheral Interface ■ Flexible Clock controller for OSD, Data Slicer and Core clocks running from one single low frequency external crystal. ■ Enhanced Display Controller with 26 rows of 40/80 characters – Serial and Parallel attributes – 10x10 dot Matrix, 512 ROM characters, definable by user – 4/3 and 16/9 supported in 50/60Hz and 100/120 Hz mode – Rounding, fringe, double width, double height, scrolling, cursor, full background color, halfintensity color, translucency and half-tone modes ■ Teletext unit, including Data slicer, Acquisition Unit and 8 Kbytes TDSRAM for Data Storage ■ VPS and Wide Screen Signalling slicer ■ Integrated Sync Extractor and Sync Controller ■ 14-bit Voltage Synthesis for tuning reference voltage ■ Up to 8 External Interrupts plus 1 non-maskable interrupt ■ 8 x 8-bit programmable PWM outputs with 5V open-drain or push-pull capability ■ 16-bit Watchdog timer with 8-bit prescaler ■ One 16-bit standard timer with 8-bit prescaler ■ 4-channel Analog-to-Digital converter; 5-bit guaranteed ■ Rich instruction set and 14-Addressing modes Versatile Development Tools, including ssembler, Linker, C-compiler, Archiver, Source Level Debugger and Hardware Emulators with RealTime Operating System available from third parties
