STC8G1K08A-36I-SOP8

STC8G1K08A-36I-SOP8 is the SOP-8 ordering code for the STC STC8G1K08A enhanced 1T 8051 microcontroller, named in full - code and package together - in the section heading of the STC8G series manual published on stcmicro.com (§2.3) and in the maker’s own product-page selection table. It runs from 1.9 V to 5.5 V with 8 KB of flash, 1.2 KB of SRAM, 4 KB of EEPROM, an internal high-precision IRC oscillator spanning 4 MHz to 36 MHz with ±0.3 % error at 25 °C, and a 10-bit ADC with 6 channels in this SOP-8 form sampling at up to 500K samples per second, with at most 6 GPIO pins, over -40 °C to +85 °C. The selection point is pin economy: a full 1T 8051 with its own oscillator, EEPROM and ADC in an 8-pin body for auxiliary control jobs - key scanning, small motor or sensor supervision, charger housekeeping - where a larger MCU package buys nothing. Selection advice: STC publishes no lifecycle grading, so qualify the code against the current manual revision at design-in; the same device is also documented in DFN8 and DIP8 forms, so the SOP8 suffix must be quoted in full to fix the footprint, and the ADC channel count given here is the SOP-8 figure, not the larger-package count. Parameters verified against the STC STC8G series manual (selection table and features).
