![]() ![]() There’s three “reaches” for addressing - short (one-byte), long (two-byte), and extended (three-byte) - trading off memory area with performance. The claim to fame of the core is its comprehensive list of 20 addressing modes, including indexed indirect addressing and stack-pointer-relative modes. ![]() There’s a 32-bit-wide program memory bus which can fetch most instructions in a single cycle - and pipelined fetch/decode/execute operations permit many instructions to execute in a single cycle. The STM8 has a Harvard architecture, but uses a unified address space. The STM8 core has six CPU registers: a single accumulator, two index registers, a 24-bit program counter, a 16-bit stack pointer, and a condition register. Additional 8-bit basic timer, auto-wake-up timer, and beeper module.Three 16-bit timers (including an advanced control timer) with 9 channels of capture, compare, and PWM.16 MHz core with 32 KB of flash, 2K of RAM, and 128 bytes of byte-addressable EEPROM.The part I’m looking at in this review, though, is the STM8S005K6, which has an even better collection of features: suppliers sell the part in similar quantities for just north of $0.50 / unit should indicate the tremendous bargain the STM8 is. Yes, that works out to 22 cents a piece for an 8K flash / 1K RAM microcontroller with 20 pins, 7 CAPCOM channels, 128 bytes of EEPROM, and 5 channels of 10-bit 430 ksps analog-to-digital conversion. I recently spent 72 Yuan (~$11) on 50 of the most famous STM8 part: the STM8S003F3P6. ST has been dumping the STM8 in the Chinese market, so it’s one of the cheapest general-purpose microcontroller you can buy these days (and that includes parts from STC and Holtek - two staples found in low-cost products made in China). There are three families - the “S” mainstream line, the “A” atomotive line, and the “L” low-power line. Support for STLINK-V3 has been added.The STM8 is ST’s family of 8-bit microcontrollers. The static analysis tool C-STAT has been updated with 20 additional rules, a number of bugfixes and better reporting function.
