Overview
(cont.)
Microcontroller Bus Interface
The PSD813FN/FH easily interfaces with most popular eight and sixteen-bit
microcontrollers with either multiplexed or non-multiplexed address/data busses. The
PSD813FH is for multiplexed applications and the PSD813FN is for non-multiplexed
applications. The PSD813FN/FH can operate with 16-bit MCUs if the MCU is configured for
8-bit external data path mode. The device is configured to respond to the microcontroller
control signals which are also used
as inputs to the PLDs.
Memory
The PSD813FN/FH contains a 1 Mbit Flash memory, a 256 Kbit Boot EPROM and a 4 Kbit
SRAM. The EPROM space and Flash memory space are divided into four and eight equally
sized blocks, respectively. Each block can be located in a different address space defined
by the user. The access time of either memory includes the address latching and DPLD
decoding. The Flash memory is implemented using a 4 Mbit (29040) device configured as a
1 Mbit memory. All the commands for the 29040 are applicable for operating as a 1 Mbit
Flash memory.
The 4 Kbit SRAM may be used as a scratch pad memory and an extension of the
microcontroller SRAM. The SRAM data is retained in the event of a system power down,
provided a backup battery is connected to the Vstby pin (PC2). Switching from the V
CC
supply to standby power occurs automatically when V
CC
drops below Vstby voltage.
Page Register
The four-bit Page Register expands the address range of the microcontroller by sixteen
times. The paged address can be used as part of the address space to access external
memory and peripherals or internal EPROM, SRAM and I/O.
Power Management Unit
The Power Management Unit (PMU) in the PSD813FN/FH enables the user to control the
power consumption on selected functional blocks based on system requirements. The PMU
includes an Automatic Power Down unit (APD) that will turn off device functions due to
microcontroller inactivity in one of two modes: the Power Down mode and Sleep mode.
Other power saving features, such as the CMiser in the PMU, allow the EPROM/SRAM to
operate at a slower rate to conserve power.
