ST72104G1

The ST72104G1 is designed as one kind of 8-bit MCU device that is based on a common industrystandard 8-bit core, featuring an enhanced instruction set. This device also features single-voltage FLASH memory with byte-by-byte In-Situ Programming (ISP) capability, and features true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes.

Features of the ST72104G1 are:(1)Enhanced reset system;(2)256 bytes RAM;(3)Enhanced low voltage supply supervisor with 3 programmable levels;(4)Clock-out capability;(5)3 Power Saving Modes: Halt, Wait and Slow;(6)7 interrupt vectors plus TRAP and RESET;(7)22 external interrupt lines (on 2 vectors);(8)22 multifunctional bidirectional I/O lines;(9)14 alternate function lines;(10)Configurable watchdog timer etc..

The absolute maximum ratings of the ST72104G1 can be summarized as:(1)Supply voltage: 6.5 V;(2)Input voltage on any pin: VSS-0.3 to VDD+0.3 V;(3)Storage temperature range: -65 to +150 °C;(4)Total injected current (sum of all I/O and control pins): ±20 mA;(5)Injected current on any other pin: +/- 5 mA;(6)Injected current on OSC1 and OSC2 pins: +/- 5 mA;(7)Output current source by any I/Os and control pin: -25 mA;(8)Output current sunk by any high sink I/O pin: 50 mA.
