device numbering conventions

Figure 15 illustrates the numbering and symbol nomenclature for the TMS370Cx7x family.

370

7 7

Prefix: TMS = Standard prefix for fully qualified devices

SE = System evaluator (window EPROM) that is used for

prototyping purpose

Family:

370 = TMS370 8-Bit Microcontroller Family

Technology:

C = CMOS

Program Memory Types:

0 = Mask ROM

7 = EPROM

Device Type:

7 = ’x7x device containing the following modules:

– Timer 1

– Timer 2A

– Analog-to-Digital Converter 1

Memory Size:

7 = 24K bytes

Temperature Ranges:

A = – 40

°Cto 85°C

°Cto 70°C

T= – 40

°C to 105°C

Packages:

FN = Plastic Leaded Chip Carrier

FZ = Ceramic Leaded Chip Carrier

NM = Plastic Shrink Dual-In-Line

JN = Ceramic Shrink Dual-in-Line

ROM and EPROM Option:

A = For ROM device, the watchdog timer can be configured

as one of the three different mask options:

– A standard watchdog

– A hard watchdog

– A simple watchdog

The clock can be either:

– Divide-by-4 clock

– Divide-by-1 (PLL) clock

The low-power modes can be either:

– Enabled

– Disabled

A = For EPROM device, standard watchdog, divide-by-4

clock, and low-power modes are enabled
