TMP90PH44
3. Operation
The TMP90PH44 is the OTP version of the TMP90C844 that
is replaced an internal ROM from Mask ROM to EPROM.
The function of TMP90PH44 is exactly the same as that
of TMP90C844 except the internal ROM/RAM size.
Refer to the TMP90C844 except the functions which are
not described this section.
The following is an explanation of the hardware configuration
and operation in the relation to the TMP90PH44.
The TMP90PH44 has an MCU mode and a PROM mode.
3.1 MCU Mode
(1)
Mode Setting and Function
The MCU mode is set by opening the CLK pin (Output
status).
In the MCU mode, the operation is the same as that of
TMP90C844.
(2)
Memory Map
Figure 1.1 and Figure 1.2 show the memory map of
TMP90PH44 and TMP90C844.
Figure 3.1 shows the memory map of TMP90PH44,
and the accessing area by the respective addressing
mode.
Figure 3.1. TMP90PH44 Memory Map
3.2 PROM Mode
(1)
Mode Setting and Function
PROM mode is set by setting the RESET and CLK
pins to the “L” level.
The programming and verification for the internal
PROM is achieved by using a general EPROM programmer
with the adaptor socket. The device selection (ROM
Type) should be “27256” with following conditions.
size: 256K-bit (32K x 8-bit) VPP: 12.5V TPW: 1msec
Figure 3.2 shows the setting of pins in PROM mode.
