•

16-bit modulus down counter with interrupt

2.4.8

Flash memory

The PXD10 microcontroller has the following flash memory features:

•

Up to 1 MB of burst flash memory

— Typical flash memory access time: 0 wait-state for buffer hits, 2 wait-states for page buffer miss

at 64 MHz

— Two 4 × 128-bit page buffers with programmable prefetch control

– One set of page buffers can be allocated for code-only, fixed partitions of code and data, all

available for any access

– One set of page buffers allocated to Display Controller Unit and the eDMA

— 64-bit ECC with single-bit correction, double-bit detection for data integrity

— 64 KB data flash memory — separate 4

 16 KB flash block for EEPROM emulation with

prefetch buffer and 128-bit data access port

•

Small block flash memory arrangement to support features such as boot block, operating system

block

•

Hardware managed flash memory writes, erase and verify sequence

•

Censorship protection scheme to prevent flash memory content visibility

•

Separate dedicated 64 KB data flash memory for EEPROM emulation

— Four erase sectors each containing 16 KB of memory

— Offers Read-While-Write functionality from main program space

— Same data retention and program erase specification as main program flash memory array

2.4.9

Static random-access memory (SRAM)

The PXD10 microcontrollers have up to 48 KB general-purpose on-chip SRAM with the following

features:

•

Typical SRAM access time: 0 wait-state for reads and 32-bit writes; 1 wait-state for 8- and 16-bit

writes if back to back with a read to same memory block

•

32-bit ECC with single-bit correction, double bit detection for data integrity

•

Supports byte (8-bit), half word (16-bit), and word (32-bit) writes for optimal use of memory

•

User transparent ECC encoding and decoding for byte, half word, and word accesses

•

Separate internal power domain applied to full SRAM block, 8 KB SRAM block during

STANDBY modes to retain contents during low power mode.

2.4.10

On-chip graphics SRAM

The PXD10 microcontroller has 160 KB on-chip graphics SRAM with the following features:

•

Usable as general purpose SRAM

•

Typical SRAM access time: 0 wait-state for reads and 32-bit writes
