1 INTRODUCTION
The ST7SCR and ST7FSCR devices are mem-
bers of the ST7 microcontroller family designed for
USB applications. All devices are based on a com-
mon industry-standard 8-bit core, featuring an en-
hanced instruction set.
The ST7SCR ROM devices are factory-pro-
grammed and are not reprogrammable.
The ST7FSCR versions feature dual-voltage
Flash memory with Flash Programming capability.
They operate at a 4MHz external oscillator fre-
quency.
Under software control, all devices can be placed
in WAIT or HALT mode, reducing power consump-
tion when the application is in idle or stand-by
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 micro-
controllers feature true bit manipulation, 8x8 un-
signed 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,
up to 35 I/O lines and the following on-chip periph-
erals:
– USB full speed interface with 7 endpoints, pro-
grammable in/out configuration and embedded
3.3V voltage regulator and transceivers (no ex-
ternal 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 pro-
grammable 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)
– Watchdog Timer
– 8-bit Timer (TBU)
