PSD413F Family
6-5
ADVANCE INFORMATION
The PSD413F contains two non-volatile memories (Boot and Flash) and a Standby SRAM.
The OTP Boot memory density is 8 Kbytes while the Flash memory density is 128 KBytes.
The OTP Boot memory allows for concurrent read and write operations during the time the
Flash memory is in the write or erase mode. The Flash memory includes the required
embedded write/erase operations and data polling capability. The DPLD and GPLD enable
efficient decoding to support the concurrent operation. The access time of the memories
includes the address latching and DPLD or GPLD decoding. The 16 Kbit Standby SRAM
may be used as an extension of the microcontroller SRAM and also to store backup infor-
mation that is necessary after a system power down or power failure. Standby power to the
SRAM is supplied by the Vstby pin. Switching between V
CC
and Vstby occurs automatically.
A four bit Page Register enables microcontrollers with limited address space easy access
to the I/O Section, Boot EPROM, Flash memory and SRAM memory. The Page Register
outputs are connected to all ZPLDs and can be used to page external devices as well as
the internal PSD413F functional sections.
A Power Management Unit (PMU) in the PSD413F enables the user to control the
power consumption on selected functional blocks based on system requirements. For
microcontrollers that cannot generate a Chip Select input (CSI) to the peripheral device,
the PMU includes an Automatic Power Down unit (APD) that will turn off the PSD413F
(to standby mode) based on inactivity of the ALE. The polarity of ALE inactivity can be
configured by the user.
The PSD413F family is supported by the WSI PSDsoft development system (see Figure 2)
which runs under MS-Windows
or Windows 95
on the PC. Design entry is done using
PSDabel which creates a minimized logic implementation. PSDabel also provides logic
simulation. The PSD413F desired configuration is entered using a simple Windows based
menu. The PSDcompiler, which consists of a Fitter and an Address Translator, generates an
object file from the PSDabel and configuration files. The object file can be down loaded to a
programmer (MagicPro
III or third party).
