MPN Structure
Sitronix MPNs follow this general structure:
[PREFIX][SERIES][MODEL][VARIANT][PACKAGE]
| | | | |
| | | | +-- Package suffix (S=SOP, V=LQFP, R=QFN)
| | | +-- Optional variant letter or revision
| | +-- Model number (65, 89, 20, etc.)
| +-- Series digits (75, 77, 79, 16)
+-- ST prefix (all Sitronix products)
Example Decoding
ST7735S
| | ||
| | |+-- S = SOP package
| | +-- (no variant)
| +-- 7735 = TFT display driver model
+-- ST = Sitronix prefix
ST7920-0B
| | |||
| | ||+-- B = COG package
| | |+-- 0 = revision/option
| | +-- hyphen separator
| +-- 7920 = Graphic LCD controller
+-- ST = Sitronix prefix

Naming Pattern Conflicts
ST vs STMicroelectronics
IMPORTANT: Both Sitronix (Taiwan) and STMicroelectronics (Europe) use the "ST" prefix!
Sitronix patterns: ST followed by 2-digit series + 2-digit model
- ST75xx, ST77xx, ST79xx (display controllers)
- ST16xx (LED drivers)
STMicroelectronics patterns: STM prefix or different number patterns
- STM32Fxxx (microcontrollers)
- STM8xxx (8-bit MCUs)
- L78xx (voltage regulators)
How to distinguish:
// Sitronix: ST + specific series numbers
"^ST(75|77|79|16)[0-9]{2}[A-Z0-9-]*$"
// STMicroelectronics: STM prefix or different patterns
"^STM[0-9].*" // MCUs
"^L78[0-9]{2}.*" // Regulators
Handler Implementation Notes
Pattern Matching
// ST75xx - TFT LCD controllers
"^ST75[0-9]{2}[A-Z0-9-]*$"
// ST77xx - TFT display drivers
"^ST77[0-9]{2}[A-Z0-9-]*$"
// ST79xx - Graphic LCD controllers (includes ST7920)
"^ST79[0-9]{2}[A-Z0-9-]*$"
// ST16xx - LED drivers
"^ST16[0-9]{2}[A-Z0-9-]*$"
Package Code Extraction
// Step 1: Handle hyphenated suffixes (ST7920-0B)
int hyphen = mpn.indexOf('-');
String basePart = hyphen >= 0 ? mpn.substring(0, hyphen) : mpn;
// Step 2: Extract suffix from ST[0-9]{4}[letters]
Pattern packagePattern = Pattern.compile("^ST[0-9]{4}([A-Z]+)$");
// Step 3: Map single-letter codes
switch (code) {
case "S": return "SOP";
case "V": return "LQFP";
case "R": return "QFN";
case "B": return "COG";
}
Series Extraction
Returns the first 4 characters (ST + 2 digits):
- ST7735S -> "ST77"
- ST7920 -> "ST79"
- ST1628 -> "ST16"

Common Use Cases
Embedded Display Projects
Sitronix controllers are widely used in:
- Arduino/Raspberry Pi displays: ST7735 (1.8" TFT), ST7789 (2.0" TFT)
- Character LCDs: ST7920 (128x64 with Chinese fonts)
- LED segment displays: ST1628
Popular Development Modules
| Module | Controller | Resolution | Interface | |--------|------------|------------|-----------| | 1.8" TFT | ST7735 | 128x160 | SPI | | 2.0" TFT | ST7789 | 240x320 | SPI | | 2.4" TFT | ST7789V | 240x320 | SPI | | 12864 LCD | ST7920 | 128x64 | Parallel/SPI |
Learnings & Edge Cases
- ST7735 vs ST7735S: The "S" is the package code (SOP), not part of the model number.
- ST7920 variants: ST7920-0B has hyphenated option code; the "0" is a revision, "B" is COG package.
- Sitronix vs STMicro: Always check the number pattern - Sitronix uses ST[75|77|79|16]xx while STMicro uses STM[8|32] or other prefixes.
- Display resolution: The model number sometimes hints at resolution capability, but datasheet verification is required.
- COG/COF packages: These are bare die packages for direct bonding, common in display applications.
