ST7 8位单片机ST7LCRDIE6

The ST7LCRE4U1 and ST7LCRDIE6 devices are members of the ST7 microcontroller family designed for USB applications. All devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set. ST7LCRE4U1 and ST7LCRDIE6 are factory-programmed ROM devices.

They operate at a 4 MHz external oscillator frequency. Under software control, all devices can be placed in Halt mode, to reduce power consumption when the application is in idle or standby state. The enhanced instruction set and addressing modes of the ST7 offer both power and flexibility to software developers, enabling the design of highly efficient and compact application code.

In addition to standard 8-bit data management, all ST7 microcontrollers feature true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes.The devices include an ST7 Core, up to 16 Kbytes of program memory, up to 512 bytes of user RAM and the following on-chip peripherals:USB full speed interface with 7 endpoints, programmable in/out configuration and embedded 3.3 V voltage regulator and transceivers (no external components are needed) ISO7816-3 UART interface with programmable baud rate from 372 clock pulses up to 11.625 clock pulses Smartcard supply block able to provide programmable supply voltage and I/O voltage levels to the smartcards Low voltage reset ensuring proper power-on or power-off of the device (selectable by option) 8-bit Timer (TBU) ST7LCRE4U1 and ST7LCRDIE6 are 8-bit microcontrollers dedicated to smartcard reading applications. They have been developed to be the core of smartcard readers communicating through USB link. Optimized for mass-market applications, it offers a single integrated circuit solution with very few external components
