Am29240EH Microcontroller
The Am29240EH microcontroller has the following addi-
tional features:
2-Kbyte, two-way set-associative data cache
Single-cycle 32-bit multiplier for faster integer
math; two-cycle Multiply Accumulate (MAC)
function
16-entry on-chip Memory Management Unit
(MMU) with one Translation Look-Aside Buffer
4-channel double-buffered DMA controller with
queued reload
Two serial ports (UARTs)
Bidirectional bit serializer/deserializer
20- and 25-MHz operating frequencies
Am29243EH Microcontroller
The Am29243EH data microcontroller is similar to the
Am29240EH microcontroller, without the video inter-
face. It includes the following features:
2-Kbyte, two-way set-associative data cache
Single-cycle 32-bit multiplier for faster integer
math; two-cycle MAC
32-entry on-chip MMU with dual TLBs
4-channel, double-buffered DMA controller with
queued reload
Two serial ports (UARTs)
20- and 25-MHz operating frequencies
DRAM parity
Am29245EH Microcontroller
The low-cost Am29245EH microcontroller is similar to
the Am29240EH microcontroller, without the data cache
and 32-bit multiplier. It includes the following features:
16-entry on-chip MMU with one TLB
Two-channel DMA controller
One serial port (UART)
Bidirectional bit serializer/deserializer
16-MHz operating frequency
