About STC:

STC89xx series, which is produced by STC MCU Limited, is a 8-bit single-chip microcontroller with a fully compatible instruction set with industrial-standard 80C51 series microcontroller. There is 64K bytes flash memory embeded for appliaction program, which is shared with In-System-Programming code.In-SystemProgramming (ISP) and In-Application-Programming (IAP) support the users to upgrade the program and data in system. ISP allows the user to download new code without removing the microcontroller from the actual end product;IAP means that the device can write non-valatile data in Flash memory while the application program is running. There are 1280 bytes or 512 bytes on-chip RAM embedded that provides requirement from wide field application. The user can configure the device to run in 12 clocks per machine cycle, and to get the same performance just as he uses another standard 80C51 device that is provided by other vendor, or 6 clocks per machine cycle to achieve twice performance. The STC89xx series retain all features of the standard 80C51. In addition, the STC89xx series have a extra I/O port (P4 ), Timer 2, a 8

STC 8051s vs Other 8051s

STC 8051s, as stated, offers additional hardware peripherals when compared to standard 8051s. There are some STC microcontrollers like STC89C52RC that are same as the standard ones while some others like STC8A8K64S4A12 are more robust with many advanced features. Some key differences between standard 8051s and STC micros are discussed below:

Packages / Sizes

STC offers microcontrollers in various DIP and SMD IC packages. Thus, instead of using a 40-pin DIP package microcontroller to solve a problem that can be solved with an 8-pin SMD low cost microcontroller, we can avoid using a big microcontroller and thereby save valuable PCB space. Most STC 8051s are, by the way, 100% pin-compatible with other 8051s. This feature makes STC micros easy and viable replacements for devices that use standard 8051s.

Speed / Operating Frequency

STC microcontrollers are relatively faster than common 8051s as they can operate at higher clock frequencies. For example, AT89S52 has a maximum operating frequency of 33MHz while STC89C52RC can be clocked with an 80MHz source.

Additional Hardware Peripherals

Some STC microcontrollers have in-built ADC, EEPROM, watchdog timer, external interrupt pins and other peripherals. Some are even equipped with higher storage capacities. These are not available in typical 8051s.

All STC chips are 8051 core derivatives, they cannot be programmed using Arduino IDE. You can compile C based programs for the device with SDCC (public domain) and download with a serial device, these days that means a USB to serial converter plus a switch and some diodes which is well documented in the STC literature. Yes, you could use an Arduino for its USB to serial converter but that's more expensive and harder to use than say a FT232 or CH340 breakout board.

 

All STC chips have a pre-installed, non-erasable bootloader and STC publishes their own downloader software STC-ISP, it's free but it's a Windows only program. There is also a public domain program called STCGAL which allows you to download programs using Linux or OSX.

Operating Voltage

Most 8051 micros need 4.0 C 5.5V DC supply voltage. Some can operate with 3.3V supplies too. Same goes for STC micros. However, there are some STC micros that are designed to operate at yet lower voltage levels. STC offers low power MCUs that operate between 2.0 C 3.6V and general-purpose micros that can operate between 3.6 C 5.5V. The operating voltage ranges and low power consumption figures of STC micros make them well-suited for battery and solar-powered devices.

Programming Interface

Most 8051s require a parallel port programmer while some require serial port programmer or separate dedicated programmer hardware. STC micros on the other hand can be programmer with a serial port programmer and so there is no need to buy a dedicated programmer. A simple USB-TTL serial converter can be used to load codes into STC micros.

Other Minor Differences

Other areas of differences include added/reduced functionalities/features. In some STC micros, there additional options for GPIOs, timers, etc while in some other devices these extras are not observed. For example, in STC89C52RC, there is 13-bit timer mode for timers 0 and 1 but this feature is absent in STC15L204EA. Likewise in STC15L204EA, there are many ways for setting up GPIOs which are not present in STC89C52RC.
