Device configuration and ordering information
Each device is available for production in user programmable versions (Flash) as well as in
factory coded versions (FASTROM).
ST7PLITEU05 and ST7PLITEU09 devices are Factory Advanced Service Technique ROM
(FASTROM) versions of ST7LITEU05 and ST7LITEU09 devices : they are factory-
programmed XFlash devices.
ST7FLITEU05 and ST7FLITEU09 XFlash devices are XFlash versions of ST7LITEU05 and
ST7LITEU09 devices. They are shipped to customers with a default program memory
content (FFh).
The FASTROM factory coded parts contain the code supplied by the customer. This implies
that Flash devices have to be configured by the customer using the Option Bytes while the
FASTROM devices are factory-configured.
Option bytes
The two option bytes allow the hardware configuration of the microcontroller to be selected.
The option bytes can be accessed only in programming mode (for example using a standard
ST7 programming tool).
Option byte 1
Bits 7:6 = CKSEL[1:0] Startup clock selection.
This bit is used to select the startup frequency. By default, the Internal RC is selected.
Table 78.
Bit 5 = Reserved, must always be 1.
Bit 4 = Reserved, must always be 0.
Bits 3:2 = LVD[1:0] Low voltage detection selection
Table 79.
These option bits enable the LVD block with a selected threshold as shown in
