In-System
Programming (ISP)
Flash Programming and
Erasure
4129N–CAN–03/08
With the implementation of the User Space (FM0) and the Boot Space (FM1) in Flash
technology the T89C51CC01 allows the system engineer the development of applica-
tions with a very high level of flexibility. This flexibility is based on the possibility to alter
the customer program at any stages of a product’s life:
•
•
Note:
This In-System-Programming (ISP) allows code modification over the total lifetime of the
product.
Besides the default Boot loader Atmel provide to the customer also all the needed Appli-
cation-Programming-Interfaces (API) which are needed for the ISP. The API are located
also in the Boot memory.
This allow the customer to have a full use of the 32-Kbyte user memory.
There are three methods of programming the Flash memory:

Figure 25. Flash Memory Mapping
Before mounting the chip on the PCB, FM0 Flash can be programmed with the
application code. FM1 is always pre programmed by Atmel with a bootloader (chip
can be ordered with CAN bootloader or UART bootloader).
Once the chip is mounted on the PCB, it can be programmed by serial mode via the
CAN bus or UART.
The Atmel bootloader located in FM1 is activated by the application. Low level API
routines (located in FM1)will be used to program FM0. The interface used for serial
downloading to FM0 is the UART or the CAN. API can be called also by the user’s
bootloader located in FM0 at [SBV]00h.
A further method exists in activating the Atmel boot loader by hardware activation.
See Section “Hardware Security Byte”.
The FM0 can be programmed also by the parallel mode using a programmer.
