• Manufacturer Part Number: SAK-TC1197-256F180E
• Description: 32-Bit Single-Chip Microcontroller
• Manufacturer: INFINEON [Infineon Technologies AG]

In TC1197 the PMU1 contains 2 Mbyte of Program Flash realized as one Flash bank. It
does not contain any Data Flash.
Since in TC1197 the two PMUs can work in parallel, further combinations of concurrent
operations are supported if those are operating on Flash modules in different PMUs, e.g.

•
Both, the Program Flash and the Data Flash, provide error correction of single-bit errors
within a 64-bit read double-word, resulting in an extremely low failure rate. Read
accesses to Program Flash are executed in 256-bit width, to Data Flash in 64-bit width
(both plus ECC). Single-cycle burst transfers of up to 4 double-words and sequential
prefetching with control of prefetch hit are supported for Program Flash.
The minimum programming width is the page, including 256 bytes in Program Flash and
128 bytes in Data Flash. Concurrent programming and erasing in Data Flash is
performed using an automatic erase suspend and resume function.
A basic block diagram of the Flash Module is shown in the following figure.
Figure 4
All Flash operations are controlled simply by transferring command sequences to the
Flash which are based on JEDEC standard. This user interface of the embedded Flash
is very comfortable, because all operations are controlled with high level commands,
such as “Erase Sector”. State transitions, such as termination of command execution, or
errors are reported to the user by maskable interrupts. Command sequences are
